Yeast works fastest when the dough itself sits at 30–35 °C; manage that number and the two rises largely manage themselves.
Instant dry yeast has a working window, and it is narrower than most kitchen advice suggests. Above 54 °C it stops working entirely; below 15 °C it slows so sharply that a recipe's times stop meaning anything. The fastest activity sits at 30–35 °C, and that is the temperature the dough itself — not the room, not the water alone — should reach after mixing.
The practical lever is a thermometer in the dough straight after mixing. If the reading lands under 15 °C, expect the bulk to drag; if the mixing water went over 54 °C, no warmth or waiting will restart the rise.
Once mixed, bulk fermentation runs 3–5 hours at 24–26 °C. The dough should come out of bulk 50–70% risen — visibly grown and still elastic, not doubled. Doubling spends strength the oven stage still needs.
On narrow screens, swipe or scroll the plate sideways.
After shaping, the final proof takes 1–2 hours. A dough that is fully proofed before it reaches the oven bakes into a flat loaf, because the rise is already spent; err on the side of slightly under rather than over.
Very wet doughs change the rules. Above 85% hydration the flour turns to paste, and instead of a warm, fast bulk the dough needs a long, cold bulk proof to build structure slowly.
If a loaf has already come out flat, the fix is next time's clock: shorter bulk, shorter proof, bake while spring remains. For the bake itself — oven settings, steam and pull temperatures — see the oven temperature and internal doneness page, and the home page puts these times back into the full six-step sequence.
