Baking worksheet

Course code S1-C5 — one large baguette-style loaf: preshape, extended shaping, scoring, and steam
Link to S1-C4 S1-C4 studied the flavor of flour; S1-C5 returns to a lean white formula and makes dough handling and crust the main skill
Hypothesis the same simple flour/water/salt/yeast becomes noticeably more interesting if you build an elongated baguette shape, the right scores, strong steam, and an active crust
Formula 400 g flour, 280 g water, 8 g salt, 3 g fresh yeast; dough about 691 g
Poolish 200 g flour + 200 g water + 0.5 g fresh yeast, 11–12 hours until a dome and the first signs of collapse
Main variable not the flavor of the preferment as such, but baguette technique: preshape, tension, scoring, steam
Lesson theory the baguette system: an elongated shape changes the crust-to-crumb ratio, tension holds the gas, the final proof leaves a strength reserve, and scoring and steam control opening
Process theory the poolish gives a familiar fermentation base, but the main flavor must come from shape, a strong crust, correct scoring, and crust drying after steam
Professional standard work as in a teaching kitchen: goal before mixing, workstation setup, dough observations, hand demonstration, grading rubric, and one conclusion for the next repeat
Hydration 70%: above the previous baseline lessons, but without moving to ciabatta
Format 1 large home baguette-batard from the entire dough mass; a convenient single piece, not a classic thin bakery baguette
Final proof short and attentive: the piece should feel lighter but not spread in the cloth
Bake 250 °C with steam for the first 10 minutes, then 220 °C dry for 18–25 minutes to a confident crust and 96–98 °C internal
Success criterion one even elongated piece, thin crackly crust, open scores, light chew, crust flavor stronger than S1-C2

Lesson block: how to read this lesson

Each bread in the course should be more than a recipe: one main question, one controlled variable, measurements, tasting, and a decision for the next bake.

Lesson question
What this bread is supposed to teach.
Main variable
One lever: fermentation, flour, water, salt, mixing, shaping, steam, scald, or sourdough.
Why this way
This keeps the result comparable and preserves cause and effect.
Expected flavor
Name the expected direction of flavor and texture before baking.

Theory

  • The formula is read in baker’s percentages.
  • Timing is checked against dough state, temperature, and sensory signs.
  • Photos and numbers exist to drive the next decision, not only to archive the bake.

Checkpoints

  • Record temperature, mass, time, dough state, and deviations.
  • After baking, assess crust, crumb, aroma, flavor, and aftertaste.

Sensory

Crust
color, thickness, crunch, score opening, bitterness, toastiness
Crumb
moisture, elasticity, gumminess, chew, pore size and distribution
Aroma
separate crust and crumb aroma: floury, yeasty, milky, rye, malty, spicy
Flavor
sweetness, salt, acidity, flouriness, depth, aftertaste
Score
0–10 plus one decision: repeat, increase fermentation, change flour, change bake, or close the lesson

What comes next

  1. The next lesson should change one main parameter and test a clear hypothesis.
Course-frame sources

S1-C5 is the first baguette lesson in the wheat track. The task here is not to make a perfect French baguette on the first try, but to set aside as a dedicated lesson the skills that used to live in the background: preshape, stretching, scoring, steam, and crust.

What This Lesson Studies

In S1-C2 the poolish was already the main flavor lever. In S1-C5 the poolish becomes a familiar base, and the new question is different: can the same simple lean formula become more tasty and expressive thanks to shape, a thin crust, and the right score opening?

The main lesson variable is dough handling and baking, not a new flour, sourdough, or enrichment.

Why One Large Piece

A home oven does not have to imitate a bakery oven. The entire mass of this dough yields not a classic thin baguette but a large home baguette-batard: elongated shape, longitudinal overlapping scores, steam, and an active crust, but more mass and a longer bake.

The formula should not be divided by a third for the sake of one small baguette: the poolish would then need about 0.17 g of fresh yeast, and the final dough about 0.83 g. That is inconvenient and less reliable on a home kitchen. So the current sheet keeps normal gram amounts and makes one piece from the entire dough mass.

What we simplifyWhat we keep
dividing into three piecespreshape and rest
micro-doses of yeast on recalculationthe original formula and convenient gram amounts
working with several piecesextended shaping
classic thin geometryelongated baguette logic
perfect appearancelongitudinal overlapping scores
a steam-injection ovenstrong hand steam and a hot stone

So the lesson stays home-scale but trains real baguette skill without unnecessary fuss with several pieces.

The Baguette System: Theory

A baguette is not just an elongated loaf. With the same flour, water, salt, and yeast, the geometry of the bread changes: the piece becomes thinner, surface relative to mass grows, the crust dries faster and takes a larger share of flavor. That is why a baguette can feel more expressive than a round or oval loaf on a similar formula.

In S1-C5 it is important to look at the whole system.

ElementWhat it doesWhat would be an error
PoolishGives a familiar fermentation base and bread aroma without new acidityTreating the poolish as the main lesson and overlooking shape errors
Mass and formatEntire dough mass goes into one piece, without recalculating yeastTrying to make a thin bakery baguette out of 690 g of dough
PreshapeSets initial direction and light tensionMaking a tight mini-loaf and meeting resistance during stretching
RestRelaxes gluten before elongationStretching immediately and tearing the surface
Final shapeCreates an even tube with tension and a seamPressing out all gas or leaving a shapeless strip
Final proofBrings the piece to lightness while leaving a strength reserveOverproofing to collapse or underproofing to density
ScoringGives a controlled opening pointCutting across or too shallow
SteamDelays crust setting in the first minutesBaking dry from the start and getting weak opening

The main takeaway: if a baguette did not open, do not immediately change the formula. First work through proof, tension, score angle, score depth, steam, and stone preheat.

S1-C5 Lab Protocol

Before starting, record the hypothesis: an elongated shape, correct scoring, and steam should give a more expressive crust and flavor than S1-C2, without changing the genre of the bread.

StageWhat to recordWhy
Poolishstart time, kitchen temperature, dome, bubbles, smell, start of collapseunderstand whether the fermentation base was mature
Final mixdough temperature, tackiness, extensibility, time on Kenwooddo not blame weak shape on the recipe if the dough was overheated or undermixed
Bulk fermentationrise, gas, surface, reaction to foldsassess dough strength before preshape
Transfer from containerpiece mass, gas loss, amount of bench floursee whether volume was destroyed before shaping
Preshapedoes the cylinder hold, does it resist stretching after the restunderstand the balance of elasticity and extensibility
Final shapelength, evenness, seam, tension, endstie geometry to opening in the oven
Final prooflightness, poke test, spreading or holding the linedecide whether to bake now or give it another 5–10 minutes
Scoringnumber of scores, angle, depth, overlap, confidence of motioncheck whether an opening path was set
Bakeloading temperature, steam, moment of drying, color, internal temperatureseparate oven errors from dough errors
Tastingcrunch, crust aroma, chew, flavor compared to S1-C2understand whether technique gave a real flavor result

This is not bureaucracy. In a professional kitchen, recording is needed so that the teacher or chef can say not “it came out bad” but “you lost gas at preshape” or “the score was too crosswise”.

Advanced Technological Map

S1-C5 has four technological axes. If you do not separate them, it is easy to treat the wrong problem.

AxisWhat controls the resultProfessional criterion
Fermentationpoolish maturity, dough temperature, bulk, final proofdough alive but not tired; aroma clean, without sharp alcohol
Rheologybalance of extensibility and elasticity, rest after preshape, gluten strengthpiece stretches without tearing and does not snap back immediately
Geometrymass, length, evenness, seam, endspiece even, holds its line, with no thick ends
Bake physicsstone, steam, crust drying, color, internal temperaturethe score opened before the crust set, then the crust dried and crackled

If the baguette is dense, it may be fermentation or rough handling. If it is flat, it may be proof or weak shaping. If the score did not open, it may be blade angle, weak steam, or overproof. A strong school teaches exactly this kind of diagnosis.

Formula

IngredientGrams%
Flour400100
Water28070
Salt82
Fresh yeast30.75

Poolish: 200 g flour, 200 g water, and 0.5 g fresh yeast. Final dough: the entire poolish, 200 g flour, 60 g water in the initial mix, 20 g water for the yeast slurry, 8 g salt, and 2.5 g fresh yeast.

70% water is the first step toward a more open baguette crumb, but still without the complexity of ciabatta. If the dough feels soft, do not add flour right away: softness is needed here for stretching and opening.

The poolish matters more than the clock: it must be bubbly, alive, with a bread aroma, domed or just starting to collapse.

Shaping

Baguette shaping is not one motion but a chain.

  1. Turn out the whole dough as one piece.
  2. Gently preshape into an elongated cylinder.
  3. Let the dough relax for 15 minutes.
  4. Fold and seal the piece, creating light tension.
  5. Roll from the center to the ends to oven size without squeezing out all gas.

If the piece resists, give it another 5 minutes of rest. If the surface tears, the tension is too aggressive.

Proof, Gas, and Strength

For baguette form, a short final proof is not accidental. A large loaf can stand a calmer proof because it has more mass and less surface relative to volume. A large baguette-batard is more stable than a thin baguette, but it still cannot be overproofed: if the piece loses its line in the cloth, the scores will open more weakly.

The goal of the proof in S1-C5 is not maximum volume on the bench but the right strength reserve for the oven.

State before the ovenSignsWhat will happen in the oven
Underproofpiece dense, indentation springs back fast, shape stiffstrong tearing, dense crumb, the score may open roughly
Normal proofpiece feels lighter, slightly puffier, line still holdsscores open, crust thinner, shape stays even
Overproofpiece soft, spreads, indentation almost does not returnweak rise, flat shape, scores do not hold direction

For a first baguette lesson, a slight underproof is better than overproof. Underproof can be partially compensated with good scoring and steam; overproof more often takes strength and geometry away.

Scoring

For one large baguette-batard, 4–5 scores are enough. The beginner’s mistake is to cut across. A baguette score runs almost along the axis, at a slight angle, with overlap. It should direct the opening, not just decorate the loaf.

TraitGoodRisk
Anglealmost along the baguettecross stripes
Depthabout 5 mmscratch or a deep tear
Overlapeach next score partially crosses the previous onescattered short marks
Proofpiece light but not spreadscores do not open or the loaf flows

Steam and Crust

A baguette needs strong initial steam. Steam delays early surface drying, helps opening, and gives a thinner shiny crust. After the first 10 minutes, steam is no longer needed: the crust must be dried.

If the crust is pale, first check stone preheat, loading temperature, and drying after steam. It is too early to change the formula.

Diagnosing Errors

S1-C5 must be evaluated as a technical chain. The same defect can look like a “bad formula” while the cause was in transfer, proof, or steam.

SymptomLikely causeWhat to check in the next repeat
Piece spread in the clothweak shaping, too long a proof, too warm a doughdough temperature, proof length, tension at shaping
Scores did not openoverproof, dry start, cross or shallow scorepoke test, steam in the first minutes, blade angle and depth
Crust thick and roughtoo little steam at the start or too long dryingsteam delivery, first 10 minutes, actual oven temperature
Pale crustweak stone preheat, too short a dry phasepreheat 60–90 minutes, loading temperature, last minutes without steam
Dense crumbgas loss at preshape/shape or underproofscraper gentleness, rest after preshape, proof
Large voids under the crusttoo rough shaping or locally trapped gaseven sealing, rolling from center to ends
No flavor shiftcrust weak, steam did not work, bread sliced too earlycrust color, crunch after cooling, tasting after 30–60 minutes

How To Evaluate The Result

S1-C5 is graded not only by crumb.

What to evaluateWhat to record
Shapeis the length even, are the ends thicker
Scoredid it open, is there a direction of opening
Crustthin, crackly, color, aroma
Crumbnot raw, are there uneven voids
Flavoris the crust aroma stronger than S1-C2
Processwhere gas was lost: bulk, preshape, shape, proof, or transfer

If the shape is weak but the flavor is good, the lesson is still useful: it shows exactly where the next technical repeat should go.

Grading Rubric

S1-C5 is better evaluated not as a single overall score but as a rubric. This is closer to how a teacher or chef analyzes practical work: not “like / dislike” but through which competencies already exist and what to train next.

Competency0 points1 point2 points
Formula and setupingredients or water swapped, tools not readyformula correct but there is rushing at shaping or loadingeverything weighed, cloth/stone/steam/blade ready in advance
Poolish maturitysharp alcohol, heavy collapse, or undermaturitypoolish workable but peak uncleardome/bubbles/smell clear and recorded
Dough after mixingoverheated, torn structure, lots of correcting flourdough workable but tackiness or strength not describedsoft, stretchy, not overheated, state recorded

Proofobvious under- or overproof without a decisionproof acceptable but signs weakly describeddecision made by lightness, poke test, and geometry
Scoringcross, random, or too shallow scoresdirection close but depth/overlap unstable4–5 confident overlapping scores almost along the axis
Steam and bakedry start, pale or rough crustbread baked but crust not idealstrong initial steam, then drying, crust thin and crackly
Sensory and conclusionno comparison or next decisiontasting present but conclusion generalgrading tied to process and one focus chosen for the next repeat

Interpretation is simple: 0–8 points — repeat without changing the formula and train hands; 9–14 — recipe workable but pick one technical weakness; 15–18 — lesson closed, move to S1-C6: ciabatta or the next baguette iteration.

Control Questions

Before baking and after cooling, answer the questions in writing in the comments of the working sheet.

  1. Was the poolish bubbly, domed or starting to collapse, without a sharp alcohol smell?
  2. Was the dough after the final mix soft and stretchy but not overheated?
  3. During transfer from the container and preshape, was gas preserved or was the dough roughly crushed?
  4. After preshape, did the piece relax and stretch without tearing?
  5. Did the final shape give an even tube with light tension, not a tight loaf?
  6. Did the proof end when the piece felt lighter but still held its line?
  7. Did the scores run almost along the axis with overlap, not across?
  8. Was steam strong at the start, and did the oven become dry after 10 minutes?
  9. Did the crust come out thin, crackly, and aromatic?
  10. Did the crust flavor become stronger and more interesting than in S1-C2?

Automatic calculation from USDA + Skurikhin database for the baked loaf after evaporation. Numbers are approximate: 1) the database covers ingredients, not finished dough; 2) bake water loss is assumed at 10% — actual loss depends on crust, time, and pan. Add 5–10% in calorie trackers if needed.

Bread is a source of starch and energy. Its nutrition depends on flour, fermentation, salt, enrichment, serving size, and the rest of the plate.

Digestion
More whole grain, fibre, and fermentation usually mean longer satiety. White flour eaten alone is generally digested faster.
Helpful or harmful
Bread is not poison or medicine by itself. Overall diet matters; current guidance prioritizes whole grains, vegetables, fruits, and pulses.
Amount
For most learning tastings, 1–2 slices, about 30–80 g, is enough depending on loaf density.
Best pairings
Pair with protein, vegetables, and moderate fat; avoid making it a large standalone portion with sweet drinks or sweet spreads.

How to eat

  • Taste the bread plain for learning, then eat it as part of a balanced plate.
  • Slice dense rye thinner; with soft white bread, make sure softness does not automatically increase the serving.

Limits

  • Wheat and rye breads contain gluten.
  • For medical conditions, adjust bread type and serving size with a clinician or dietitian.

Instructions

  1. Mix the poolish

    Mix 200 g flour, 200 g water, and 0.5 g fresh yeast, cover, and leave overnight until domed and bubbly.

  2. Build the final dough

    Mix the entire poolish, 200 g of flour, and 60 g of water; rest for 20 minutes.

  3. Add yeast and salt

    Crumble 2.5 g of fresh yeast into 20 g of water, stir, and add to the dough; mix 30–60 seconds, then add 8 g of salt and finish a short mix to smoothness and extensibility.

  4. Bulk ferment

    Run about 2 hours with 1–2 gentle folds, preserving gas and controlling temperature.

  5. Preshape

    Turn out the whole dough as one piece, gently preshape into an elongated cylinder, and let it rest.

  6. Shape a single piece

    Shape a large home baguette-batard sized for the oven, place in a dusted cloth, and proof 35–45 minutes.

  7. Score and bake

    Make 4–5 overlapping longitudinal scores, give strong steam at the start, and bake for 10 minutes at 250 °C with steam, then 18–25 minutes at 220 °C dry to 96–98 °C internal.

S1-C5: bake sheet for one home-scale baguette

Evening poolish and daytime bake: learn to preshape, elongate one large baguette piece, make overlapping scores, and give steam. The main result is technique and crust, not a new addition to the formula.

Schedule mode

Pick a starting style.

  1. Day 1, 20:30–20:35

    Poolish

    Mix 200 g flour, 200 g water, and 0.5 g fresh yeast to a uniform mass with no dry flour. Cover and leave at room temperature.

    Step ingredients

    • MukaMuka 13.5% flour 200 g
    • Water 200 g
    • Fresh yeast 0.5 g
    Target
    Poolish uniform, level marked, container covered.
    Check
    Yeast is intentionally low: the poolish must mature overnight, not collapse within a few hours.
    Evidence
    Start time, kitchen temperature, poolish consistency.
  2. Day 1, 20:35 (Day 2 08:30)

    Poolish maturation

    Leave the poolish until morning. By the final mix it should be bubbly, slightly domed, or just starting to collapse.

    Step ingredients

    • Poolish all of it: 200 g flour + 200 g water + yeast
    Target
    Many small bubbles, bread aroma, lively surface.
    Check
    If the poolish has dropped sharply and smells of alcohol, you can still bake it, but record it as overmaturity.
    Evidence
    Smell, time of readiness.

    11 h 55 min timer for this step

  3. Day 2, 08:30–08:38

    Final mix start

    In the Kenwood bowl combine the entire poolish, 200 g of flour, and 60 g of the final water on Min until no dry flour remains.

    Step ingredients

    • Poolish all
    • MukaMuka 13.5% flour 200 g
    • Water 60 g out of the final 80 g
    Target
    Dough rough and sticky, but all flour hydrated.
    Check
    Do not add salt and final yeast yet: let the flour briefly take up water.
    Evidence
    State after hydration.
  4. Day 2, 08:38–08:58

    Short rest

    Cover the bowl and leave the dough for 20 minutes.

    Step ingredients

    • Dough without salt and final yeast all of it
    Target
    Dough has become more cohesive without rough mechanical mixing.
    Check
    Do not shorten the rest: extensibility matters for a baguette, not just strength.
    Evidence
    Actual rest duration and change in consistency.

    20 min timer for this step

  5. Day 2, 08:58–09:05

    Salt, yeast, and final mix

    Crumble 2.5 g of fresh yeast into 20 g of the final water, stir to a slurry, and add to the dough. Mix 30–60 seconds on Min to distribute, then add 8 g of salt and mix on Kenwood Min/1 for about 4–5 minutes.

    Step ingredients

    • Fresh yeast 2.5 g
    • Water 20 g out of the final 80 g
    • Salt 8 g
    • Dough after rest all of it
    Target
    Dough smooth, elastic, stretchy but still soft and not overheated; dough temperature after mixing 24–25 °C.
    Check
    Do not aim for a tight ball: a baguette dough needs extensibility and gas, not a dense bun-like structure.
    Evidence
    Dough temperature, tackiness, extensibility.
  6. Day 2, 09:05

    Bulk fermentation start

    Transfer the dough to a lightly oiled container, round with a scraper, and cover.

    Step ingredients

    • Dough about 691 g
    Target
    Dough gathered, surface smooth, bulk start recorded.
    Check
    If the dough is very warm, do the next checks earlier.
    Evidence
    Dough and kitchen temperature.
  7. Day 2, 09:50

    Fold 1

    Make one gentle fold in the container: pull the edge of the dough to the center without squeezing out gas.

    Step ingredients

    • Dough after 45 minutes of bulk all of it
    Target
    Dough is more gathered but does not tear.
    Check
    If the dough is tight and tears, fold more gently or skip the second pass.
    Evidence
    Elasticity and extensibility after the fold.
  8. Day 2, 10:35

    Fold 2

    Repeat a gentle fold if the dough is spreading. If it already holds well, limit yourself to a light edge pull.

    Step ingredients

    • Dough after the first fold all of it
    Target
    Dough holds shape better, surface lively.
    Check
    The main thing is to keep the gas. Do not turn the fold into a new mix.
    Evidence
    Dough state, bubbles, strength.
  9. Day 2, 11:05–11:20

    Preheat and preshape

    Turn the oven on to 250 °C with stones or a heavy sheet pan. Turn out the whole dough as one piece and gently preshape into an elongated cylinder without dividing.

    Step ingredients

    • Dough after bulk all of it, about 691 g
    • Bench flour minimal, not part of the formula
    Target
    One piece with light tension and preserved gas.
    Check
    Do not try to stretch 690 g of dough into a classic thin baguette: this is a large home baguette-batard sized for the oven.
    Evidence
    Piece mass and preshape state.
  10. Day 2, 11:20–11:35

    Rest after preshape

    Cover the piece and let it relax for 15 minutes.

    Step ingredients

    • Preshaped piece 1 piece
    Target
    Dough has relaxed and is ready to be stretched without tearing.
    Check
    If the piece resists, give it another 5 minutes rather than tearing it during shaping.
    Evidence
    Extensibility after the rest.
  11. Day 2, 11:35–11:50

    Final shape

    Shape one large home baguette-batard sized for your oven: flatten minimally, fold the upper third, seal, repeat, then roll gently from the center to the ends. In a couche place it seam-up so that on transfer it lands seam-down; if proofing directly on parchment, place it seam-down from the start.

    Step ingredients

    • Rested piece 1 piece
    • Couche cloth 1 piece, well dusted
    Target
    Piece evenly stretched, with light tension, ends not thicker than the middle.
    Check
    Because of the dough mass, do not chase fine bakery geometry: it is better to get an even large baguette-batard than to tear the surface.
    Evidence
    Length, tension, evenness of shape.
  12. Day 2, 11:50–12:30

    Final proof

    Proof in the cloth for 35–45 minutes. The piece should feel lighter and slightly puffier but still hold its line.

    Step ingredients

    • Shaped baguette-batard 1 piece
    Target
    Underproof is safer than overproof: the scores must open in the oven.
    Check
    If the dough spreads in the cloth, bake earlier. If it is dense and cold, give it another 10 minutes.
    Evidence
    Poke test, lightness of the piece, geometry.

    40 min timer for this step

  13. Day 2, 12:30–13:05

    Score and bake

    Transfer the piece onto parchment or a board seam-down. Make 4–5 overlapping scores almost along the axis, at a small angle, about 5–7 mm deep. Add steam and bake at 250 °C for 10 minutes, then at 220 °C dry for another 18–25 minutes to color and 96–98 °C internal.

    Step ingredients

    • Proofed baguette-batard 1 piece
    • Steam water for steam, not part of the formula
    Target
    Scores opened, crust thin and crackly, color confidently golden-brown.
    Check
    Scores should run almost along the baguette with overlap, not across. Steam is needed at the start, then dry the crust.
    Evidence
    Internal temperature, bake time.

    35 min timer for this step

  14. Day 2, 13:05–14:05

    Cool, slice, and taste

    Cool at least 45 minutes, better 60. Slice the bread and evaluate crust, score opening, chew, aroma, and flavor.

    Step ingredients

    • Finished baguette-batard 1 piece
    • New ingredients none added
    Target
    Understand whether baguette technique gave a more expressive crust and an interesting flavor without enrichment.
    Check
    Evaluate on baking day, but do not slice hot: a single large piece needs more time for the crumb to stabilize.
    Evidence
    Mass after baking, weight loss, tasting note.

For readers who want to understand why the formula changed.

S1-C5 hypothesis

S1-C5 tests how much handling and bake technique change a simple lean bread. The formula stays close to previous lessons, while the new skill is baguette shape, scoring, and steam.

Base version

S1-C2 already tested poolish as a flavor lever, S1-C3 cold, S1-C4 the whole-grain share. Now we need a lesson that separates the flavor of the formula from the flavor of crust and handling quality.

Iteration analysis

01 A baguette lesson can be run with a single home-scale piece
Observation
A classic thin baguette is longer and lighter than is convenient to shape and bake from the entire mass of this dough in a home oven.
Hypothesis
If we make one large baguette-batard, we can preserve the main lesson skills — preshape, extended shape, scoring, steam, and crust — without awkward dividing and without micro-doses of yeast.
Decision and why
Lesson format: 1 large home baguette-batard from the entire dough mass, about 691 g raw.
Conclusion
The single large format is more convenient for home repeats: it honestly remains baguette practice, but does not pretend to be a classic thin French baguette.
Evidence
Home constraint
stone/sheet pan and hand steam instead of a bakery oven
Learning goal
shape, scoring, and crust, not industrial size or strict classical geometry
02 Keep the poolish as a familiar base
Observation
Poolish was already studied in S1-C2, but the main question there was flavor.
Hypothesis
If we use a familiar poolish in S1-C5, the new variable becomes baguette technique, not the type of preferment.
Decision and why
Selected an overnight poolish of 200 g flour + 200 g water + 0.5 g fresh yeast.
Conclusion
Leave old dough for a separate comparison if the poolish version gives a manageable shape.
Evidence
Preferment
50% of total flour in the poolish
New topic
preshape, shaping, scoring, steam
03 Scoring and steam become measurable skills
Observation
In previous lessons, crust and scoring were secondary, not the main object of the lesson.
Hypothesis
If we make overlapping longitudinal scores and strong initial steam, the piece will open better and give a thinner crust.
Decision and why
The working sheet adds photos of scores before loading, opening after baking, and a separate crust evaluation.
Conclusion
If the scores did not open, first work through proofing, blade angle, and depth before changing the formula.
Evidence
Scoring
4–5 overlapping scores almost along the axis
Steam
strong initial steam, then dry baking

Version history

  • v1.8May 23, 2026
    Problem
    After S1-C7 was published, the older explanation still sounded as if old dough was only a possible future variation of S1-C5.
    Change
    FAQ and lesson route synchronized with the new program: S1-C5 remains the poolish and baguette-technique lesson, while old dough is studied separately in S1-C7.
    Result
    S1-C5 no longer conflicts with the published S1-C7 and keeps a clear learning role.
    Conclusion
    Poolish, old dough, and sourdough opara should run as different learning variables, not be mixed in one first baguette lesson.
  • v1.7May 20, 2026
    Problem
    Three mini-baguettes were inconvenient for home repeats when one piece is wanted.
    Change
    The formula was left without recalculation to avoid awkward yeast fractions. The entire dough mass is now shaped into one large home baguette-batard; baking has been extended to 250 °C with steam for 10 minutes + 220 °C dry for 18–25 minutes to 96–98 °C.
    Result
    The working sheet now leads to a single piece and keeps convenient gram amounts; only shaping, number of scores, bake length, and cooling change.
    Conclusion
    For strict practice of classic baguette geometry it is better to divide the dough into several pieces, but the basic home S1-C5 sheet is now built around one convenient piece.
  • v1.6May 20, 2026
    Problem
    Variant v1.5 with crumbling fresh yeast straight onto the dough is acceptable in a mixer mix, but for the home sheet it looks unusual and less predictable.
    Change
    Final water has been split into 60 g for the initial mix and 20 g for a convenient yeast slurry. The micro-step with 5 g of water is not coming back.
    Result
    Yeast is distributed more naturally and cleanly, without a separate micro-vessel and without the risk of leaving a noticeable share of yeast on the walls.
    Conclusion
    For S1-C5, treat introducing the final yeast through 20 g of water as the basic home protocol; direct crumbling stays as a permissible professional alternative, not the main instruction.
  • v1.5May 20, 2026
    Problem
    Adding 2.5 g of fresh yeast through 5 g of water was inconvenient: too small a vessel is needed, the yeast does not dissolve well, and part of the slurry stays on the walls.
    Change
    The final water now all goes into the initial hydration, and fresh yeast is crumbled directly onto the dough and briefly mixed in before salt. The formula and overall hydration have not changed.
    Result
    The step has become easier for a home kitchen and closer to professional practice with fresh yeast: it can either be dissolved in enough liquid or crumbled directly into the dough at mixing.
    Conclusion
    S1-C5 no longer requires a separate micro-cup with 5 g of water; control rests on even yeast distribution and dough temperature.
  • v1.4May 19, 2026
    Problem
    Theory already explained the baguette system, but the lesson was not yet framed as a professional teaching laboratory with goals, demonstration, protocol, and a grading rubric.
    Change
    Added blocks on the professional teaching format, lab protocol, advanced technological map, and grading rubric modeled on a strong bread school.
    Result
    S1-C5 can now be run as a learning module: state a hypothesis before mixing, record critical points during work, and grade after baking against the rubric.
    Conclusion
    The next repeat should improve one specific competency, not simply repeat the whole recipe.
  • v1.3May 19, 2026
    Problem
    S1-C5 was detailed enough as a recipe, but the theory of baguette form was weaker than the standard of S1-C2/S1-C3: it lacked an explicit link between shape, tension, proof, scoring, and steam.
    Change
    Added a separate S1-C5 learning profile, expanded baguette-system theory, and added error diagnostics and pre-bake control questions.
    Result
    The lesson now explains not only what to do, but also why baguette geometry, proof, scoring, and steam should give a more expressive crust and flavor.
    Conclusion
    S1-C5 becomes a full theoretical lesson on baguette technique, not only a working sheet for mini-baguettes.
  • v1.2May 19, 2026
    Problem
    Starting the poolish at 21:00 gave finished baguettes around 14:25, which is a bit late for lunch bread and less convenient for first baguette practice.
    Change
    The working sheet was shifted to a poolish start at 20:30: final dough begins at 08:30, baking at 12:30, cooling until 13:55.
    Result
    The best baseline start window is now 20:00–20:30 in the evening if you need bread for an early lunch the next day.
    Conclusion
    The formula has not changed; only the more convenient start scenario has shifted.
  • v1.1May 19, 2026
    Problem
    A repeat review showed three places where the recipe could lead to wrong action: salt was described as dissolved in 5 g of water, the seam during proofing was ambiguously specified, and prep time did not match actual time to loading.
    Change
    Clarified the addition of final yeast and salt, set seam orientation for the couche and parchment, and brought prep time to 16 hours from poolish start to oven loading.
    Result
    Formula, percentages, and time map remained unchanged; the instructions became technologically more precise.
    Conclusion
    S1-C5 is correct as the first baguette teaching lesson: the main check no longer gets confused with technical ambiguities.
  • v1.0May 19, 2026
    Problem
    After S1-C4, the next wheat-track lesson should move from flour flavor to baguette handling: preshape, extended shape, scoring, and steam.
    Change
    Created S1-C5: three home mini-baguettes on overnight poolish, 70% water, without enrichment, sourdough, whole-grain flour, or cold retard of the final dough.
    Result
    Working sheet ready for poolish start on 19 May at 21:00 and a bake the next day.
    Conclusion
    The main S1-C5 check is not a perfect French baguette but transferable skill: even shape, correct scoring, steam, and a crackly crust.

Questions

Why a poolish again, if it was already in S1-C2?

In S1-C2 the poolish was the main flavor lever. In S1-C5 it becomes a stable base for baguette technique: shaping, scoring, steam, and crust.

Why one piece and not three mini-baguettes?

It is more convenient for home repeats and does not require dividing the dough. Be honest about format: 691 g of raw dough gives a large home baguette-batard, not a classic thin bakery baguette.

Why is old dough not part of this lesson?

S1-C5 must leave baguette technique as the new variable: shape, scoring, and steam. Old dough is moved into S1-C7 as a separate lesson on old dough, salt in the preferment, and overall baker's percentages.

How many scores should I make?

For one large piece, 4–5 overlapping scores are enough. Direction matters more than count: scores run almost along the axis, slightly angled, and overlap.

What counts as success?

Even shape, opened scores, a thin crackly crust, a stronger crust aroma, and a crumb without rawness. A perfectly open crumb in the first lesson is not required.
