Tools Needed

• Digital kitchen scale
• Large mixing bowl
• Danish dough whisk or wooden spoon
• Banneton basket or floured bowl
• Dutch oven (6 qt)
• Bread lame or sharp knife
• Parchment paper
• Cooling rack

Step-by-Step Instructions

1. Feed Your Starter

Feed starter 4-6 hours before mixing, using a 1:1:1 ratio (50g starter, 50g flour, 50g water). It should double in size and bubble vigorously. Keep at 70-75°F (21-24°C). If cooler, use a 1:5:5 ratio for overnight rise.​

2. Mix the Dough

Combine water and lemon juice in a large bowl. Stir in active starter until dissolved. Rub lemon zest with sugar to release oils, then add to bowl with flour and salt. Mix with a whisk or hands until no dry flour remains; dough looks shaggy. Cover and rest 30 minutes (autolyse).​

3. Stretch and Folds

Wet hands. Grab one edge, stretch up, and fold over center. Rotate bowl 90 degrees; repeat 3 more times. Rest 30 minutes. Do 1-2 more sets. On second set, gently add blueberries, folding them in without bursting. Cover between sets. Dough strengthens and smooths.​

4. Bulk Fermentation

Cover bowl; let rise at room temperature (68-75°F) 10-14 hours until 75% increased: domed top, bubbles on sides, jiggly when shaken. Warmer room? Check at 8 hours. Colder? Extend to 16 hours. Avoid full doubling to prevent overproofing.​

5. Shape the Loaf

Flour counter lightly. Turn out dough seam-side up. Gently stretch to rectangle. Fold bottom third up, sides in, top down like envelope. Flip seam-side down. Cup hands around; rotate to tighten surface, tucking blueberries inside. Place seam-up in floured banneton. Cover.​

6. Cold Proof

Refrigerate 8-48 hours. Longer proof deepens sour flavor. Ready when puffy and passes poke test (indent springs back slowly).​

7. Bake

Preheat oven to 450°F (230°C) with Dutch oven inside for 45 minutes. Invert dough onto parchment. Score top 1/2-inch deep at 30-degree angle for ear. Lift into hot pot (lid on). Bake 25 minutes. Remove lid; bake 10-15 minutes more until deep golden (internal 205°F/96°C). Tap bottom for hollow sound. Cool on rack 2+ hours.​

Sample Baking Schedule

Adjust for your routine; watch dough signs over clock.

Time Slot	Action	Duration/Notes
8:00 AM	Feed starter (1:1:1)	Peaks by 2:00 PM ​
2:00 PM	Mix dough, first folds	After peak rise ​
3:00-5:00 PM	Additional folds, bulk start	Room temp ​
Next Day 6:00 PM	Shape, fridge	Overnight cold proof ​
Day 3, 6:00 PM	Bake	After 24-48 hr fridge ​

Troubleshooting Tips

• Dense loaf? Starter weak; test float next time. Use warmer spot.
• Berries burst? Handle gently during folds; use fresh over frozen.
• Flat rise? Underfermented; extend bulk. Overproofed dough? Shape loosely or make focaccia.
• Gummy crumb? Cut cooling short; always 2 hours minimum. Pale crust? Extend lid-off bake.​

Storage and Serving

Store cut-side down under towel up to 2 days. Bread box or bag for longer. Refresh: Spritz water, 450°F oven 10 minutes. Freeze whole/sliced up to 3 months; thaw at room temp, refresh. Slice for toast with butter, cream cheese, or lemon curd. Try French toast: soak stale slices in egg-milk mix, fry golden.​

Frequently Asked Questions

Can I use frozen blueberries?
Yes, thaw and drain well; add 10-20g extra water as they release moisture. Pat dry to avoid purple dough.​

What if I lack a Dutch oven?
Bake on preheated stone with steam pan (1 cup hot water). Or use covered casserole. Crust softer but still great.​

Sourdough discard instead?
Sub equal unfed discard for starter; expect milder tang, longer bulk rise. Best cold proofed 24+ hours.​

Vegan?
Fully vegan as written. Use maple for sugar if preferred.​

Add lemon curd?
Layer spoonfuls during shaping; bake 5-10 extra minutes for moisture. Divine swirl!​

Bread flour unavailable?
All-purpose: reduce water 25g. Whole wheat: sub 100g max for nutty flavor, no hydration change.​
