Starter and salt percentages are calculated from the total flour, including flour in the starter. Whole wheat percentage applies to the fresh flour you add. Your normal starter is 100% hydration (equal weights of flour and water).

Our simple bread-making method
  1. Use the starter near peak, or just beginning to fall.
  2. Mix starter with water, then add the flours and salt. Mix by hand for 3–5 minutes.
  3. Cover for 30 minutes. Do three gentle stretch-and-fold sets, about 30 minutes apart.
  4. Continue bulk fermentation until the dough is adequately risen and aerated. Time depends on starter activity and dough temperature.
  5. Pre-shape gently. Rest 15–20 minutes, final-shape, then transfer to a floured proofing basket.
  6. Cover and refrigerate at about 4°C overnight. Bake straight from the fridge in a thoroughly preheated Dutch oven.
  7. For a 1 kg loaf, start with 25 minutes covered at 240°C, then 20–30 minutes uncovered at 220°C. Adjust for loaf size and oven.
