Ingredients:
- 100g active sourdough starter
- 340g warm water
- 500g bread flour
- 10g fine sea salt
- 20g granulated sugar
- zest of 2 large lemons
- 125g fresh or frozen blueberries
Instructions:
- Prepare the citrus sugar. Rub the lemon zest into the 20g sugar with your fingertips until the sugar looks like wet sand and smells like a lemon grove. Note: This releases the essential oils for better flavor distribution.
- Mix the base. Whisk 100g starter into 340g warm water, then stir in the lemon sugar and 500g bread flour until no dry streaks remain.
- The Autolyse rest. Let the shaggy mass sit for 30 minutes. Note: This allows the flour to fully hydrate and makes the dough easier to handle.
- Add the salt. Sprinkle 10g salt over the dough and dimple it in with wet fingers, folding the dough over itself until the texture feels smooth and elastic.
- Stretch and folds. Over the next 2 hours, perform 4 sets of folds (one every 30 mins) by pulling the edge of the dough up and over the center until the dough holds its shape in a ball.
- The Lamination. Gently stretch the dough into a large rectangle on a damp counter and scatter 125g blueberries over the surface until evenly covered.
- Bulk Ferment. Fold the dough back into a ball and let it rest in a warm spot (about 24°C) until it has grown by 50% and feels bubbly.
- Shape and Cold Proof. Shape into a tight round, place in a floured basket, and refrigerate for 12-15 hours. Note: This long rest develops the deep, tangy sourdough flavor.
- Preheat and Score. Heat your Dutch oven to 230°C. Flip the cold dough onto parchment and slash the top with a blade until you see a clean, 1cm deep cut.
- The Final Bake. Bake with the lid on for 20 mins, then lid off for 25 mins until the crust is deep mahogany and the berries are sizzling.
