01 - In a large bowl, combine bread flour and water. Stir until just blended. Cover and let rest for 45 minutes to allow the flour to hydrate.
02 - Add the active sourdough starter and fine sea salt. Mix thoroughly until the dough is cohesive and no dry spots remain.
03 - Cover and allow the dough to rest for 30 minutes, supporting gluten development.
04 - Perform 3 to 4 sets of stretch and folds every 30 minutes over the next 2 hours. Each set strengthens the dough and builds structure.
05 - Cover the bowl and let the dough rise at room temperature for 4 to 6 hours, or until the dough has doubled in volume and appears bubbly.
06 - Lightly flour your work surface and gently turn out the dough. Shape it into a round or oval loaf, handling carefully to preserve air pockets.
07 - Place the shaped dough seam-side up in a well-floured proofing basket or medium bowl. Cover loosely and refrigerate for 8 to 12 hours for optimal flavor and crumb texture.
08 - Place a Dutch oven or baking stone inside your oven and preheat to 450°F (230°C). Allow sufficient time for thorough heating.
09 - Turn the proofed loaf out onto parchment paper. Using a sharp blade or bread lame, score the surface to allow controlled expansion during baking.
10 - Carefully transfer the scored dough into the hot Dutch oven. Cover and bake for 20 minutes to produce steam, essential for a crisp crust.
11 - Remove the lid and continue baking for an additional 20 to 25 minutes, until the loaf develops a deep golden coloration and crust.
12 - Transfer the baked loaf onto a wire rack. Allow to cool completely to set the crumb before slicing.
