Bread and Dough Production
Bread and dough production covers everything from formula construction through mixing, bulk fermentation, makeup and bake-off for lean and enriched doughs. The exam tests whether you can read a formula, control dough temperature, judge gluten development by feel and by window test, and diagnose faults at the bench instead of by guesswork.
Formula logic
Flour is always 100%. A typical lean bread runs water 65–72%, salt 1.8–2.2%, fresh yeast 0.5–2% (or 0.2–0.7% instant), depending on fermentation length. Enriched doughs add fat 5–20% and sugar 5–15%; both tighten gluten and slow fermentation, so mixing and proof times extend.
Dough temperature
Dough temperature drives fermentation rate. For a straight dough with two added masses plus friction, water temperature = (3 × desired dough temperature) − room temperature − flour temperature − friction factor. Friction is measured, not guessed: mix a batch and record the temperature rise.
Development and makeup
Stages run from pickup through clean-up and improved mix to intensive mix. Lean doughs are usually taken to a full windowpane; enriched doughs to improved mix so they can still expand. Shaping builds surface tension; scoring cuts at a shallow angle to control where the loaf opens.
Worked example
Formula: flour 1000 g, water 68%, salt 2%, instant yeast 1%. Water = 0.68 × 1000 = 680 g; salt 20 g; yeast 10 g; total 1710 g. Desired dough temperature 24 °C, room 22 °C, flour 21 °C, friction 6 °C. Water temperature = (3 × 24) − (22 + 21 + 6) = 72 − 49 = 23 °C.
Traps
Treating salt as a percentage of total dough rather than of flour; adding yeast to hot water; judging proof by the clock instead of the dough; and overmixing enriched dough until the gluten breaks down.
