Ingredients
Method
- In a large bowl, mix together the flour, water, starter, and rosemary until no dry bits remain. Cover and rest 30 minutes.
- Add salt and optional olive oil. Perform a set of stretch and folds, then repeat twice at 30-minute intervals over 90 minutes.
- Cover and let the dough bulk ferment at room temperature for 4 to 6 hours, until doubled and bubbly.
- Turn dough onto a floured surface, shape into a round, rest 20 minutes, then shape tightly and place seam-up in a floured banneton.
- Proof covered for 1 to 2 hours until puffy. Preheat a Dutch oven to 450°F (230°C), turn loaf onto parchment, score, mist with water, and bake covered for 30 minutes then uncovered 10 to 15 minutes until deep golden. Cool completely on a rack.
Notes
The listed prep and cook times do not include the 5 to 8 hours of fermentation and proofing, which are largely hands-off. Use an active, bubbly starter for the best oven spring and tangy flavor.
