Ingredients
Method
- In a large bowl, mix bread flour, lukewarm water, sugar, and active sourdough starter until a rough, shaggy dough forms.
- Cover the bowl and let the dough rest for 30 minutes at room temperature to allow the flour to fully hydrate.
- Sprinkle the salt over the dough, then gently fold in the blueberries and lemon zest using a stretch-and-fold motion.
- Knead gently for 1–2 minutes, just until the salt and add-ins are evenly distributed.
- Cover and let the dough bulk ferment for about 3 hours, performing 3–4 stretch and folds during this time.
- Shape the dough into a tight round and place seam-side up into a floured banneton. Cover and refrigerate for 8–12 hours.
- Preheat the oven to 450°F (232°C) with a Dutch oven inside. Invert the dough onto parchment and score the top.
- Bake covered for 25 minutes, then uncover and bake another 25 minutes until deep golden brown.
- Cool the loaf completely on a wire rack for 3–4 hours before slicing.
Notes
Use fresh blueberries for best results, as frozen berries can bleed into the dough. For added depth, substitute up to 30% of the flour with whole wheat. If you don’t have a Dutch oven, bake on a sheet pan with an inverted roasting pan to trap steam.
