Method

  1. 01 · Feed

    6–8 hours

    Use: A

    Keep only 100 g mature levain. Mix in the feed flour and water; cover at room temperature.

    Ready when: Bubbly, expanded and webbed inside; pleasantly fermented.

    Baker stirs a thick, softly flecked levain in a clear container.
    01 FeedMix the retained starter with its feed flour and water, then cover and let it expand.

  2. 02 · Roast nuts

    About 12 minutes; start ≥1 h before autolyse

    Use: C

    Roast walnuts at 205°C; cool completely before the dough mix.

    Ready when: Fragrant and browned, without bitterness or scorched edges.

    Walnut halves and pieces are roasted until browned, then left to cool.
    02 Roast nutsRoast the walnuts until browned and fragrant, then cool them completely before adding.

  3. 03 · Autolyse

    20–30 minutes

    Use: B flour + B water

    Near the end of the feed, mix the final-dough flours and water only. Cover. Keep salt, yeast and levain aside.

    Ready when: All flour moistened; no dry pockets.

    Seen from the side, the baker mixes rough pale wheat dough by hand in a clear rectangular tub.
    03 AutolyseMoisten all the final-dough flour with the final water, then cover and rest.

  4. 04 · Mix

    3–6 minutes

    Use: Autolysed dough + remaining B

    With a damp hand, fold edges over the additions; pinch through the mass with thumb and forefinger 5–6 times. Alternate pinching and folding until uniformly mixed, about 3–6 minutes. Rest briefly, then fold again.

    Ready when: Uniform dough, no streaks of levain or salt.

    From an elevated angle, the baker pinches and folds cohesive pale wheat dough in a clear tub.
    04 MixUse a damp hand to pinch and fold the levain, salt and any listed yeast evenly into the dough.

  5. 05 · Add walnuts

    10-minute rest, then incorporate

    Use: Mixed dough + cooled C

    Rest mixed dough 10 minutes. Scatter cooled walnuts over it; pinch and fold gently until distributed.

    Ready when: Even distribution without large torn areas.

    Cooled walnut pieces are scattered over the soft dough before folding in.
    05 Add walnutsScatter the cooled walnuts over the rested dough, then pinch and fold gently to distribute them.

  6. 06 · Fold & bulk

    3 sets in first 1½–2 h; total bulk about 5 hours

    Use: Mixed dough

    With a damp hand, stretch one edge until resistance, then fold across the dough. Repeat around 4–5 sides; turn the bundle seam down. Cover between sets; let it relax before the next set. Do not tear it or fold during the last bulk hour.

    Ready when: About 2½× starting volume, aerated and elastic.

    The baker lifts a short elastic flap of walnut-studded dough, ready to fold it back across the mass.
    06 Fold & bulkLift an edge gently, fold it across, then let the dough relax before the next set.

  7. 07 · Divide & shape

    After bulk

    Use: Fermented dough

    Gently tip onto a lightly floured counter and divide equally. Fold each perimeter inward; turn seam down. Cup and drag on an unfloured patch, rotating, until the surface holds tension without tearing. Place seam DOWN in floured baskets; cover.

    Ready when: Medium-tight rounds; preserve visible gas.

    The baker cups one walnut-studded dough round with a second equally sized round beside it.
    07 Divide & shapeDivide equally and cup each piece into a smooth round, then place seam down in floured baskets.

  8. 08 · Proof

    12–14 hours

    Use: Covered baskets

    Refrigerate in closed bags overnight. Bake directly from the fridge; no warm-up is needed.

    Ready when: Expanded, aerated loaves; firm enough to lift while cold.

    The baker places a pair of bag-covered walnut-studded dough rounds in proofing baskets into the refrigerator.
    08 ProofEnclose the baskets in closed bags and refrigerate overnight. Bake the loaves directly from the fridge.

  9. 09 · Preheat

    At least 45 minutes, overlapping final proof

    Use: Oven + covered Dutch ovens

    Put covered pots on a middle rack. Preheat thoroughly to 245°C.

    Ready when: Oven and pot fully heated.

    Two covered cast-iron pots heat on the middle oven rack.
    09 PreheatHeat the covered Dutch ovens thoroughly while the loaves finish proofing.

  10. 10 · Bake

    30 min covered + about 20 min uncovered

    Use: Proofed loaves

    Invert onto a lightly floured counter and carefully lower into hot pot seam UP. Cover for 30 minutes, then uncover to finish. Use dry oven mitts; keep skin clear of hot iron.

    Ready when: Deep brown crust; check 15 min after uncovering.

    Using dry oven mitts, the baker lifts a lid to reveal a naturally split walnut-studded loaf, with a second covered pot nearby.
    10 BakeUse dry mitts to remove the lid after the covered bake, then finish uncovered until the crust is deep brown.

  11. 11 · Cool

    At least 20 minutes; longer for cleaner slices

    Use: Baked loaves

    Lift out of pots and cool on a rack before cutting.

    Ready when: Steam has subsided; crumb no longer tears when cut.

    One whole walnut-studded loaf and both halves of a second cool on a raised rack beside the baker.
    11 CoolCool the loaves on a rack before cutting so the crumb can set without tearing.

What to look for

StageLook and feelNeeds attention
Mix & foldsSticky but cohesive dough gains height and elasticity after each fold.A puddle that never gains strength, or a dry dough tearing under a gentle stretch.
ProofUse volume and dough feel alongside the schedule. At room temperature, a poke returns slowly and partly.Immediate rebound suggests more proof; collapse or a lasting deep dent suggests excess proof.

Troubleshooting

If you seeLikely causeWhat to do nowNext time
Dough is slow to expandCool dough or weak levain.Keep covered in a mildly warmer spot; wait for the volume cue.Confirm the starter is vigorous; log dough and room temperatures.
Loaf spreads or collapsesFermentation went too far or shaping left little tension.Handle gently and bake promptly; expect a lower loaf.Use the volume cue; shape with surface tension and shorten the next warm hold.

Recipe notes

  • Formula totals describe the final dough, not all flour used for feeding. Use only the stated levain portion. An established culture at 80% hydration with an 80:20 white-to-whole-wheat flour blend maintains that composition. After a change of feed, traces of the previous flour blend and hydration remain.
  • Keep unused levain separately for the next feeding; do not return salted dough to the starter. For one Dutch oven, chill the waiting loaf and reheat the empty pot for 5 minutes before the second bake.

Recipe

Walnut sourdough bread

Roasted walnuts added after the dough is mixed.

How do I make it?

  1. Prepare the starter

    6–8 hours

    Prepare the starter: keep only 100 g of ripe, active starter and mix in the flour and water listed for this feed. Aim for 26–27°C just after mixing, then cover and leave at room temperature. This prepared starter is the levain used later in the dough.

    Baker stirs a thick, softly flecked levain in a clear container.
    Mix the retained starter with its feed flour and water, then cover and let it expand.

    Ready when: The starter has grown, is bubbly and shows fine stretchy strands inside, with a pleasant fermented smell.

  2. Roast and cool the walnuts

    About 12 minutes; start ≥1 h before autolyse

    Roast the walnuts at 205°C. Let them cool completely before mixing the dough.

    Walnut halves and pieces are roasted until browned, then left to cool.
    Roast the walnuts until browned and fragrant, then cool them completely before adding.

    Ready when: The walnuts smell toasted and are browned, without burnt edges or bitterness.

  3. Rest the flour and water

    20–30 minutes

    As the prepared starter nears readiness, mix only the flour and water listed for the final dough. Cover and let it rest, keeping the salt, yeast and prepared starter separate for now.

    Seen from the side, the baker mixes rough pale wheat dough by hand in a clear rectangular tub.
    Moisten all the final-dough flour with the final water, then cover and rest.

    Ready when: All the flour is wet, with no dry patches.

  4. Mix the dough

    3–6 minutes

    Add the remaining group B ingredients to the rested dough, then wet your hand and fold the outer edges over them. Pinch through the dough with your thumb and forefinger 5–6 times, alternating with folds until evenly mixed, about 3–6 minutes. Rest briefly, fold again and aim for a dough temperature of 25–26°C.

    From an elevated angle, the baker pinches and folds cohesive pale wheat dough in a clear tub.
    Use a damp hand to pinch and fold the levain, salt and any listed yeast evenly into the dough.

    Ready when: The dough looks even, with no streaks of starter or salt.

  5. Mix in the walnuts

    10-minute rest, then incorporate

    Let the mixed dough rest for 10 minutes. Scatter the cooled walnuts over it, then gently pinch through and fold the dough until the nuts are spread throughout.

    Ready when: The nuts are spread evenly, without large tears in the dough.

  6. Fold and let rise

    3 folding rounds in first 1½–2 h; total first rise about 5 hours

    Wet your hand, lift one edge of the dough just until it resists, then fold it across; work around 4–5 sides and turn the dough folded-side down. Keep it covered and let it relax between rounds of folding. Avoid tearing the dough, and leave it untouched for the last hour of this first rise.

    Lift an edge gently, fold it across, then let the dough relax before the next set.

    Ready when: About 2½× its starting size, airy and stretchy.

  7. Shape the loaves

    After the first rise

    Gently tip the dough onto a lightly floured counter and divide it equally. Fold each piece’s edges into the middle, turn the folded side down onto a patch without flour, then cup and gently pull it toward you while turning until the surface is firm without tearing. Put the rounds folded-side DOWN in floured rising baskets and cover, keeping as much air in the dough as possible.

    The baker cups one walnut-studded dough round with a second equally sized round beside it.
    Divide equally and cup each piece into a smooth round, then place seam down in floured baskets.

    Ready when: Moderately firm rounds that still have air bubbles inside.

  8. Let the loaves rise

    12–14 hours

    Put the covered rising baskets in closed bags and refrigerate overnight. Bake the loaves straight from the fridge; they do not need to warm up first.

    Put the heavy lidded pots on the middle rack. Heat the oven and pots thoroughly to 245°C.

    Two covered cast-iron pots heat on the middle oven rack.
    Heat the covered Dutch ovens thoroughly while the loaves finish proofing.

    Ready when: The oven and pot are fully hot.

  10. Bake

    30 min covered + about 20 min uncovered

    Turn each loaf out onto a lightly floured counter and carefully lower it folded-side UP into a hot pot. Bake with the lid on for 30 minutes, then remove the lid to finish baking. Use dry oven mitts and keep your hands clear of the hot metal.

    Using dry oven mitts, the baker lifts a lid to reveal a naturally split walnut-studded loaf, with a second covered pot nearby.
    Use dry mitts to remove the lid after the covered bake, then finish uncovered until the crust is deep brown.

    Ready when: A deep brown crust; start checking 15 min after removing the lid.

  11. Let it cool

    At least 20 minutes; longer for cleaner slices

    Take the loaves out of the pots and leave them on a rack to cool before slicing.

    One whole walnut-studded loaf and both halves of a second cool on a raised rack beside the baker.
