Feed Starter (if needed). Feed your starter and wait until it’s active: bubbly, doubled, slightly domed, and a spoonful floats in water
In a large bowl, mix flour, water and starter until no dry bits remain. Cover and rest 30–40 minutes.
Add Salt. Sprinkle 10 g salt over the dough. With wet hands, pinch and fold until the salt dissolves and the dough tightens slightly
Every 30 minutes, with WET hands, do 1 set of turns: lift an edge, stretch up, fold over; rotate the bowl and repeat 3–4 times
Let the dough rest until risen about ~50%, surface slightly domed, tiny bubbles at edges, and a gentle jiggle when nudged. Time depends on room temp (warmer = faster)
Preshape & Rest. Lightly flour the surface. Gently turn out the dough, tuck into a loose round, and rest 20 minutes uncovered to relax
Shape into a tight boule or batard to build surface tension. Place seam-side up in a floured banneton (rice flour works best)
Proof - Preferred (deeper flavor): cover and refrigerate overnight (8–16 hours). - Same-day (milder flavor): proof at room temp 1–2 hours until slightly puffy Place the dutch oven (with lid) in the oven and preheat to 475°F (246°C) for at least 30 minutes
Turn dough onto parchment seam-side down. Dust the top lightly with flour. Score a confident ¼-inch-deep slash. Lower into the hot pot.
Bake covered 20 minutes at 475°F (246°C), then uncover and bake 18–25 minutes more until deep golden and ~208–212°F (98–100°C) internal.
Cool on a rack at least 1 hour before slicing for best crumb and texture
Enjoy!
