Ingredients
Method
- Combine flour and warm water in a large bowl. Mix until no dry flour remains. Cover and let rest for 30 minutes (autolyse).
- Add active sourdough starter and salt to the dough. Mix thoroughly by squeezing the dough through your fingers until fully incorporated.
- Perform stretch and folds every 30 minutes for 2 hours (4 sets total). For each set, grab one side of dough, stretch upward, fold over center. Rotate bowl 90 degrees and repeat 4 times.
- Cover bowl and let dough rise at room temperature for 6-8 hours until doubled in size with visible bubbles.
- Turn dough onto lightly floured surface. Shape into a round by tucking edges underneath to create surface tension. Place seam-side up in floured proofing basket.
- Cover loosely and refrigerate overnight (8-12 hours) for cold fermentation.
- Preheat oven to 450°F with Dutch oven inside for 30 minutes.
- Turn cold dough onto parchment paper. Score top with sharp blade in one confident slash about 1/2 inch deep.
- Lower dough into hot Dutch oven using parchment. Cover with lid and bake 20 minutes.
- Remove lid and bake additional 20-25 minutes until deep golden brown and internal temperature reaches 205°F.
- Cool completely on wire rack for at least 1 hour before slicing.
Notes
For best results, use a kitchen scale to measure ingredients by weight. The starter should pass the float test before using. Store baked bread cut-side down at room temperature for up to 4 days, or slice and freeze for up to 3 months.
