Ingredients:
- 100g all-purpose flour
- 100g water, at room temperature
- 500g bread flour
- 350g water, at room temperature
- 10g sea salt
- 150g sourdough starter
Instructions:
- Combine flour and water in a bowl. Mix until smooth. Cover and let it sit at room temperature overnight (8-12 hours).
- In a large mixing bowl, combine bread flour and water. Mix until fully incorporated. Cover and let it rest for 30 minutes (autolyse).
- Incorporate the sourdough starter and salt into the dough. Mix until well combined.
- Let the dough rise at room temperature, folding it every 30 minutes for the first 2 hours and then let it rest undisturbed for another 2 hours.
- Turn the dough onto a lightly floured surface and shape it into a ball. Let it rest for 30 minutes.
- Shape the rested dough again into a tight ball and place it seam-side up in a floured proofing basket or bowl. Cover and let it rise for 1-2 hours.
- Preheat your oven to 450°F (230°C) with a Dutch oven inside for at least 30 minutes.
- Carefully transfer the dough into the preheated Dutch oven (seam-side down), cover, and bake for 30 minutes. Remove the lid and bake for another 10-15 minutes until golden brown.
- Transfer the baked loaf to a cooling rack and let it cool completely before slicing.
