Breads with preferments
White bread with biga
A white loaf with 80% of its flour in a stiff overnight biga; suitable for pizza and focaccia.
Method
01 · Build biga
12–14 h at 18–21°CUse: P
Take about 44.4 mL from the measured P water to wet the P yeast in a small cup; wait a few minutes and stir. Add to P flour, rinse the cup with another little portion of measured P water, then add all remaining P water. Pinch through with thumb and forefinger, alternating with folds until incorporated. Cover at 18–21°C.Ready when: About tripled, slightly domed and dotted with gas bubbles, with a ripe fermented aroma.

01 Build bigaThe ripe biga should hold a soft dome and show gas bubbles while remaining a cohesive dough. 02 · Mix final dough
A few minutesUse: D + all mature P
Mix D flour, salt and yeast; add D water and combine briefly. Add all the mature biga. Wet your hand and alternate 5–6 thumb-and-forefinger pinch cuts with folds until the stiff biga and fresh dough are evenly blended.Ready when: Uniform dough with no unmixed lumps of preferment.

02 Mix final doughBlend all the mature biga with the fresh dough using pinch cuts and folds until the mixture is uniform. 03 · Fold and bulk
2½–3½ h from end of final mixUse: Mixed dough
Apply 2–3 sets during the first 1½ hours. For each set, wet your hand; stretch one edge upward only to resistance and fold across. Repeat around 4–5 edges until the dough firms, then turn the whole mass seam down. Let it relax before the next set. Cover between folds and during the remaining rise.Ready when: About 3 times its initial volume.

03 Fold and bulkLift one edge only until it resists, fold it across, then cover between sets. 04 · Divide and shape
A few minutesUse: Risen dough; dusting flour
Ease dough onto a lightly floured counter without tearing. Divide equally. Fold each piece’s edges inward to enclose it, turn seam down onto a clean unfloured patch, and cup and drag toward you while turning to make a medium-tight ball. Set seam DOWN in a well-floured basket; flour the top and cover.Ready when: Two rounds with moderate tension and intact surfaces.

04 Divide and shapeDivide evenly and cup each piece into a round without tearing its surface. 05 · Proof
About 1 h; preheat promptlyUse: Shaped loaves
Proof covered. Gently press the loaf with a floured fingertip to make a small dent: a slow, incomplete return indicates readiness; immediate spring-back means wait; no return with a slack loaf suggests overproofing.Ready when: Loaf aerated and expanded; indentation recovers slowly and incompletely.

05 ProofLet the rounds become puffy; a small fingertip dent should return slowly and only partway. 06 · Preheat during proof
At least 45 min at 245°CUse: Oven and lidded pots
Put lidded Dutch ovens on the middle rack and heat fully. If using one pot, refrigerate the second room-proofing loaf about 20 minutes before baking the first; reheat the empty pot 5 minutes between loaves.Ready when: Pots and oven fully heat-soaked.

06 Preheat during proofHeat the covered pots thoroughly while the loaves finish proofing. 07 · Load and bake
245°C throughoutUse: Proofed loaf
Invert the loaf onto a lightly floured counter, then carefully lower it seam UP into the hot pot, avoiding the hot sides. No scoring is needed: the seam opens naturally. Use mitts for the pot and lid. Bake covered 30 minutes, then uncovered 20–30 min. Check from 15 minutes uncovered.Ready when: Crust at least medium-dark brown all around.

07 Load and bakeThe seam opens by itself. After the covered bake, remove the lid with mitts and finish browning uncovered. 08 · Cool
At least 20 minUse: Baked loaves
Turn the bread out and cool on a rack with air beneath it. Wait at least 20 minutes before slicing; allow longer if the center is still very hot.Ready when: Crumb begins to set; crust stays aired on the rack.

08 CoolLet air circulate underneath both loaves and give the crumb time to set before slicing.
What to look for
| Stage | Look and feel | Needs attention |
|---|---|---|
| Mature biga | About tripled, slightly domed and dotted with gas bubbles, with a ripe fermented aroma. | Using a quiet, underdeveloped build or waiting until it has collapsed well past peak. |
| Bulk dough | About 3 times its initial volume. Folds should give increasing support. | Tearing the dough during folds or judging only by time. |
| Proof | A gentle finger dent returns slowly and incompletely. | Waiting until the whole loaf is fragile or collapses at a touch. |
Troubleshooting
| If you see | Likely cause | What to do now | Next time |
|---|---|---|---|
| Biga is ready too early | The room was warmer than the reference recipe’s overnight reference temperature. | Use the build at its mature stage if possible; do not deliberately leave it collapsing for hours. | Use a cooler location or adjust the next build’s water temperature and timing. |
| Little rise by the stated time | Cooler dough or room; weak or inaccurate yeast dose. | Check dough temperature and expansion. Allow more time in a gently warm place; continue only when the recipe’s volume cue is reached. | Weigh yeast carefully and record final dough temperature; adjust the next batch’s water temperature. |
| Loaf spreads or collapses at loading | Final proof went too far or shaping left insufficient tension. | Load gently and bake promptly; expect reduced height. | Begin checking early, particularly in warmth. Shape with moderate tension and refrigerate a second loaf while the first bakes. |
| Dark bottom but pale upper crust | Uneven oven heat or a rack too close to the bottom element. | Check oven temperature and finish by crust color while monitoring the base. | Use the middle rack and a fully heated pot; verify actual oven temperature. |
Recipe notes
- The P ingredients are part of the total formula. The D row saying “all of P” is a transfer, not another portion of flour, water or yeast.
- Plan the overnight rise for 18–21°C; warmer rooms shorten preferment maturity and dough rise.
- The biga is 68% hydration. Use the entire prepared build; its listed transfer weight is rounded.
- At 23°C final dough, allow about 3½ hours of bulk rise; at 26–27°C, about 2½–3 hours. Wait for the dough to triple.
- The biga weighs about 1,345 g. Total yeast in the final dough is about 2.6 g.
