The process

  1. Autolyse · 1 h

    Flour and water, mixed just until there's no dry flour left. Then wait.

  2. Starter and salt

    Add the starter, then the salt. Squeeze the dough together for 3–4 minutes with wet hands.

  3. Bulk · 4–5 h

    Around 24°C, with 3–4 sets of stretch & fold early on. Done when it has grown 50–75% and is full of bubbles.

  4. Shape · overnight

    Pre-shape, rest 20 minutes, shape tight, into the banneton. 12–16 hours in the fridge.

  5. Bake · 250°C

    In a cast-iron pot: 20 minutes lid on, then 20–25 minutes lid off at 230°C.
