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
- The next lesson should change one main parameter and test a clear hypothesis.
R1-C4 is the fourth lesson of the rye track. It is the first rye bread with a scald and red malt in the course. The main task is to see how the sweetness of the scald contrasts with the acidity of the opara and creates a characteristic scald profile before adding molasses, sugar, and caraway in R2-C1 (Borodinsky).
What This Lesson Studies
- How a scald with red malt brings out the sweetness of rye flour without sugar.
- Why the scald must be cooled to 35–40 °C before mixing.
- How the acidity of the opara and the sweetness of the scald contrast in the finished bread.
- Why coriander is optional in R1-C4 and caraway is not added until R2-C1.
Scald Theory
When rye flour and malt are poured with boiling water, two things happen:
- Starch gelatinization. Cold starch does not release water; hot rye starch in water forms a thick gel that holds moisture and makes the crumb juicier.
- Partial hydrolysis of starch to sugars. Amylase from rye malt (especially white fermented malt) breaks part of the starch into maltose and glucose. Red fermented malt has less enzymatic activity than white but gives more color and aroma.
R1-C4 uses a short scald (1 hour in a thermos), without thermostatting at 65 °C. This gives moderate sweetness, clear dark color, and simplifies the home process.
| Type of scald | Technology | What it gives |
|---|---|---|
| Short in a thermos (R1-C4) | Boiling water + 1 hour | Color, moderate sweetness, simplicity |
| 65 °C x 3 hours (R2-C1) | Thermostat | Maximum sweetness, saccharification |
| No scald (R1-C1, R1-C2, R1-C3) | None | Clean rye flavor of the starter |
Why Cool The Scald To 35–40 °C
If a hot scald (above 45 °C) ends up in the mix, the acidity of the opara drops, and lactic acid bacteria suffer thermal shock. The dough becomes sluggish, the yeast slows down, and the flavor shifts toward bland and sweetish.
On the other hand, a scald that is too cold (below 25 °C) overcools the dough; fermentation slows and the proof drags on. The optimal range is 35–40 °C: warm but not hot.
The Scald + Opara Pair
R1-C4 is built on the contrast of two prepared components:
| Component | What it carries | Share of flour |
|---|---|---|
| Sourdough opara | Gas, acidity, rye background | 20% |
| Scald with malt | Sweetness, color, aroma, water binding | 20% |
| Final dough | Structure, regulation of consistency | 60% |
If the opara is weak, the crumb will be sweet-flat. If the scald is poorly cooled or made from old malt, the acidity of the opara will overpower the sweetness.
Why Only 20% Wheat Flour
20% of wheat flour gives a minimal wheat scaffold and slightly lightens the crumb, but does not turn the bread into a 60/40 rye-wheat. This allows:
- Comparing R1-C4 with R1-C3 (100% rye) and seeing what is changed by the scald and what by the wheat flour.
- Approaching R2-C1 (Borodinsky), where wheat flour adds about 15–20% and works together with the scald and molasses.
Optional Coriander
4 g of ground coriander is a flavor note, not a profile. Unlike R2-C1, where caraway + coriander + molasses create the recognizable Borodinsky, in R1-C4 coriander is optional.
If you make R1-C4 without coriander, record it as a deviation, not as an error. This allows comparison of two versions and a decision on whether coriander belongs in this particular profile.
Lab Protocol
| Control point | What to record | Why for the scald + malt |
|---|---|---|
| Steeping (90–95 °C) | Water temperature at pour, steep time (40–60 min) | Below 85 °C — starch does not gelatinize; above 95 °C — malt loses enzymes |
| Scald cooling | Scald temperature before mixing (target 35–40 °C) | Above 50 °C kills the starter; below 30 °C — scald loses sweetness |
| Color and flavor of the scald | Rich brown, clear sweetness, red-malt aroma | Saccharification done; a pale scald means underheating |
| After 10–14 h of opara | Dome, rise 1.8–2.5 times, sour rye smell | Opara runs parallel to the scald, independent of it |
| After mix with scald | Dough temperature 28–30 °C (scald warms the dough) | A warm dough speeds up fermentation — shorter proof |
| After baking | Internal 98–99 °C, crust darkened by the malt | Maillard goes more actively with malt |
| After 12–24 h rest | Sweetness by tasting, malt aromas | Rest reveals malt notes absent in R1-C3 |
Diagnosing Errors
| Symptom | Cause for scald + malt | What to check |
|---|---|---|
| Scald pale, not sweet | Water below 85 °C or short steep | Boiling water at 95 °C, thermos 40–60 min wrapped |
| Mix killed the starter | Scald hotter than 50 °C at addition | Thermometer in the scald before mixing; wait for 35–40 °C |
| Crumb too sweet, gummy | Overdose of red malt (>5%) | R1-C4 standard is 3% of flour; reduce or switch to white |
| Dark crumb but no malt flavor | Unfermented malt used | R1-C4 needs fermented red malt specifically |
| Crust burns, crumb not baked | Maillard speeds darkening | Lower starting temperature to 240 °C; cover with foil |
| Acidity overpowers malt | Opara over-matured; acid overrides sweetness | Shorten opara to 10 h or reduce inoculum |
| Scald separates in the dough | Mix too short, scald did not disperse | Mix with K-beater 2–3 min to full uniform |
Control Questions
- Did the starter run 3 refreshments 5+10+10 → 5+15+15 → 20+85+85 and is a reserve of 15–20 g set aside in the fridge?
- Was the scald made separately from the opara: 90–95 °C, steep 40–60 min in a thermos or wrapped pot?
- Did the scald cool to 35–40 °C before mixing (checked with a thermometer, not by eye)?
- Was red fermented malt (not white, not unmalted) added into the scald, not into the opara?
- Did the opara rise 1.8–2.5 times and smell of sour rye, without vinegar?
- Was the dough after mixing a thick porridge, temperature 28–30 °C (warm because of the scald)?
- Did internal temperature reach 98–99 °C at removal?
- Was the slice made no earlier than 12 hours after baking so the malt aroma had time to develop?
Grading Rubric
| Criterion | Bad | Norm for scald + malt | Excellent |
|---|---|---|---|
| Crumb color | Pale, like R1-C3 | Dark brown, even | Deep chocolate, with sheen |
| Sweetness | Absent or cloying | Light background | Clean malty, not sugary |
| Aroma | Only sour, no malt | Sour + malty | Layered: malt, molasses-like, rye flour |
| Crumb moisture | Dry or sharply gummy | Moist, springy | Steadily moist, melting |
| Crust | Burned or pale | Dark, no burn | Glossy, with warm tones |
| Sweet/sour balance | One dominates | Balanced | Harmonious rye-flour profile |

Lesson Conclusion
If the scald + opara pair gave a balanced profile (sweetness noticeable, acidity clean, crumb stabilized in 12–24 hours) — the lesson is closed. Next step: R2-C1 (Borodinsky) with molasses, caraway, and a longer scald at 65 °C. If the scald is flat, raise the malt share or extend the scald. If the opara overpowers the scald, shorten the opara time or lower the maturation temperature.

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
-
Prepare the starter
Take the rye starter out of the fridge. Run 3 refreshments: 5+10+10 → 5+15+15 → 20+85+85; the final refreshment at peak.
-
Make the scald
100 g of rye flour and 15 g of red malt poured with 150 g of boiling water in a thermos or jar with a tight lid; steep 1 hour, then cool to 35–40 °C.
-
Set aside the reserve and build the opara
Before building the opara, set aside 15–20 g of active starter into a clean jar and put it in the fridge. Mix 100 g of rye flour, 100 g of water, and 20 g of active starter. Hold for 10–14 hours at 24–27 °C until domed with a lactic smell.
-
Mix
In the Kenwood combine the opara, the cooled scald, 130 g of water, 9 g of salt, and 4 g of coriander. Add 200 g of rye flour and 100 g of wheat flour. Mix with the K-beater on Min for 1–2 minutes to uniform.
-
Transfer into the pan
Grease the pan, transfer the dough, level with a wet spoon or wet fingers; mark the starting height and dough mass.
-
Final proof
Proof at 24–28 °C until rise of 1.5–1.8 times; usually 1.5–2.5 hours because of the scald sugar.
-
Bake
250 °C 10 minutes with steam, 200 °C 30 minutes, 170 °C 30 minutes to the first probe check; if below 98 °C inside, top up in 5-minute increments.
-
Rest
Take out of the pan, cool on a rack uncovered, wrap in cotton/linen. Do not slice before 12 hours, better 24 hours.
For readers who want to understand why the formula changed.
R1-C4 hypothesis
If a scald with red malt provides sweetness, and a sourdough opara provides acidity, a rye-wheat 80/20 will get a characteristic scald profile without molasses and sugar.
Base version
R1-C1 (60/40), R1-C2 (80% rye), and R1-C3 (100% rye) have already shown the behavior of rye sourdough without a scald and without malt. R1-C4 introduces two new variables for the first time: the scald and red malt. Coriander is kept optional so as not to mix it with the spices of R2-C1.
Iteration analysis
01 The scald brings out sweetness without adding sugar
- What went wrong
- In rye bread, sweetness is usually obtained by adding sugar or molasses. This makes the recipe more complex and reduces diagnostic clarity.
- Observation
- When rye flour and red malt are poured with boiling water, starch gelatinizes and part of it is partially hydrolyzed into simple sugars. This gives sweetness without additions.
- Hypothesis
- A scald of 100 g rye flour + 15 g red malt + 150 g boiling water will give noticeable sweetness and dark color without sugar and molasses.
- Decision and why
- Make the scald short (1 hour in a thermos) and do not heat to 65 °C — this simplifies the home process compared with R2-C1.
- Conclusion
- If sweetness without sugar is noticeable, in R2-C1 molasses can be added consciously as a new variable, not just as part of the recipe.
Evidence
- Scald
- 100 g rye flour + 15 g red malt + 150 g boiling water
- Share of flour in the scald
- 20% of the total flour
02 The pair scald + opara matters more than each component separately
- What went wrong
- If you use only the scald, the crumb will be sweet but flat. If only the opara, the profile will be sour and rye but without sweet depth.
- Observation
- The acidity of the opara contrasts with the sweetness of the scald and creates a recognizable scald rye flavor.
- Hypothesis
- An opara with 20% of the flour preferred plus a scald with 20% of the flour will give a balance of acidity and sweetness without tipping to one side.
- Decision and why
- Opara and scald carry an equal share of flour (20% each) so that their contributions are comparable.
- Conclusion
- If the pair works, in later versions the share of opara and scald can be shifted separately.
Evidence
- Opara
- 20% of the flour preferred
- Scald
- 20% of the flour in the starch gel
03 Coriander — optional note, not the main variable
- What went wrong
- In Borodinsky, coriander and caraway are mandatory components of the profile. In R1-C4 this is an extra variable if added by default.
- Observation
- 4 g of ground coriander adds aroma but does not dominate. Caraway is not added in R1-C4 to leave room for R2-C1.
- Hypothesis
- An optional coriander allows comparison of two R1-C4 versions (with and without coriander) by one recipe move.
- Decision and why
- Coriander is kept in the formula as optional with a status note; omitting it is recorded as a deviation, not as an error.
- Conclusion
- The decision on spices is postponed until R2-C1, where caraway + coriander work together with molasses and sugar.
Evidence
- Coriander
- 4 g = 0.8% of flour
- Caraway
- 0 g in R1-C4
Version history
- v1.0May 25, 2026in development
- Problem
- In the R1-C rye track, after R1-C3 (100% rye), a transition to a rye with a scald and malt is needed — without the sweetness of molasses/sugar and without the complexity of caraway, as a bridge to R2-C1 (Borodinsky).
- Change
- Created R1-C4: rye-wheat 80/20 with a scald (100 g rye + 150 g boiling water + 15 g red malt), a sourdough opara with 20% of the flour preferred, and optional coriander.
- Conclusion
- The lesson tests how the sweetness of the scald contrasts with the acidity of the opara and whether this gives a recognizable profile without adding molasses and sugar.
Questions
Why a scald in R1-C4 if there is none in R1-C1, R1-C2, and R1-C3?
The scald saccharifies part of the rye flour and brings out the sweetness; together with red malt it creates a recognizable scald rye profile. R1-C4 tests exactly how the scald works before adding molasses, sugar, and caraway in R2-C1 (Borodinsky).
Can I hold the scald at 65 °C for 3 hours as in Borodinsky?
Yes, but that is already R2-C1 technology: at 65 °C amylase is active and the scald saccharifies more. R1-C4 is simpler without thermostatting: boiling water in a thermos for 1 hour gives less sweetness but a more reproducible result for home conditions.
Can it be made without coriander?
Yes, coriander is optional. Without it the bread loses one flavor note, but the pair 'scald + malt + opara' remains the main lesson topic.
Why only 20% wheat flour?
20% of wheat flour gives a minimal wheat scaffold and slightly lightens the crumb, but does not turn the bread into a 60/40 rye-wheat. This lets you compare R1-C4 with R1-C3 (100% rye) and see what is changed by the scald and what by the wheat flour.
