Ingredients
Method
- Mix flour and water, rest 30 minutes. Add starter, salt, and sugar, then mix by hand until combined.
- Perform 4 sets of stretch and folds at 30-minute intervals over 2 hours.
- Laminate the dough on a wet surface, scatter blueberries and zest, roll, and rest 30 minutes.
- Shape into a tight boule, place in a floured banneton, and cold proof in the refrigerator 10 to 16 hours.
- Preheat a Dutch oven to 450°F (230°C). Score the dough, bake covered 30 minutes, then uncovered 15 to 18 minutes until deep amber.
- Cool completely on a rack, then slice and serve.
Notes
The hands-on time is brief, but the dough needs at least 12 hours of resting and proofing, so plan ahead. If using honey, reduce the water by 10g to keep the dough manageable. A digital scale gives the most consistent results.
