Understanding the Ingredients

Bread Flour

Bread flour contains more protein than all-purpose flour, helping create:

• Better gluten development
• Stronger structure
• Chewier texture

---

Active Sourdough Starter

Your starter should be:

• Bubbly
• Active
• Doubled in size after feeding

A healthy starter is the key to a well-risen loaf.

---

Blueberries

Fresh blueberries work best because they hold their shape during folding.

Frozen blueberries may be used but should remain frozen until added.

---

Lemons

Fresh lemons provide:

• Bright citrus flavor
• Aromatic oils from the zest
• Natural acidity

Avoid bottled lemon juice for the best flavor.

---

Step 1: Feed Your Starter

Feed your starter approximately 4–6 hours before mixing.

It should be at peak activity when used.

A strong starter ensures proper fermentation and rise.

---

Step 2: Mix the Dough

In a large bowl combine:

• Water
• Active starter

Mix until the starter dissolves.

Add:

• Bread flour

Mix until no dry flour remains.

The dough will look rough and shaggy.

Cover and rest for:

30 minutes

This stage is known as autolyse.

---

Why Autolyse Matters

Autolyse allows the flour to absorb water completely.

Benefits include:

• Improved gluten formation
• Easier dough handling
• Better crumb structure

---

Step 3: Add Salt

Sprinkle salt over the dough.

Mix thoroughly until incorporated.

The dough will begin to strengthen.

---

Step 4: Begin Bulk Fermentation

Cover the dough.

Allow it to rest for 30 minutes.

---

Step 5: First Stretch and Fold

Perform a stretch and fold.

Grab one side of the dough.

Stretch upward.

Fold toward the center.

Repeat on all four sides.

---

Step 6: Add Lemon Zest

During the second fold, gently add:

• Lemon zest
• Lemon juice

Fold carefully to distribute evenly.

The dough will become fragrant with citrus aroma.

---

Why Lemon Zest Is Important

Most lemon flavor comes from the zest rather than the juice.

The zest contains aromatic oils that provide intense citrus character.

---

Step 7: Continue Stretch and Folds

Perform three additional stretch-and-fold sessions every 30 minutes.

The dough should become:

• Smooth
• Elastic
• Strong

---

Step 8: Incorporate Blueberries

After the third fold:

Gently scatter blueberries over the dough.

Fold carefully.

Try not to crush them.

The goal is even distribution without excessive juice release.

---

Tips for Adding Blueberries

Use gentle movements.

Crushed berries can:

• Release excess moisture
• Stain the dough
• Create sticky spots

A few broken berries are perfectly fine.

---

Step 9: Complete Bulk Fermentation

Cover the dough.

Allow it to continue fermenting until increased by approximately:

50–75%

This typically takes:

4–6 hours

depending on room temperature.

---

Signs Bulk Fermentation Is Complete

The dough should:

• Look puffy
• Have visible bubbles
• Jiggle slightly
• Feel airy

These are signs of proper fermentation.

---

Step 10: Pre-Shape

Lightly flour your work surface.

Turn out the dough carefully.

Shape into a loose round.

Allow to rest for:

20 minutes

---

Why Bench Rest Matters

This resting period allows the gluten to relax.

Relaxed dough is easier to shape and creates better structure.

---

Step 11: Final Shape

Shape into:

• A boule (round loaf)

or

• A batard (oval loaf)

Create surface tension without tearing the dough.

---

Step 12: Transfer to Banneton

Dust a banneton with flour.

Place dough seam-side up.

Cover.

---

Step 13: Cold Proof

Refrigerate overnight for:

8–12 hours

Cold proofing develops:

• Flavor
• Structure
• Better scoring ability

---

Why Overnight Fermentation Improves Bread

Long fermentation produces:

• More complex flavor
• Improved texture
• Better crust development

The wait is worth it.

---

Step 14: Preheat the Oven

Place a Dutch oven inside the oven.

Preheat to:

475°F (245°C)

for at least 45 minutes.

A fully heated Dutch oven is crucial for oven spring.

---

Step 15: Score the Dough

Turn dough onto parchment paper.

Using a bread lame or sharp razor:

Make one deep slash.

Or create decorative scoring patterns.

---

Why Scoring Is Necessary

Scoring allows controlled expansion during baking.

Without scoring, the loaf may split unpredictably.

---

Step 16: Bake Covered

Transfer dough into the hot Dutch oven.

Cover immediately.

Bake for:

25 minutes

The trapped steam helps create:

• Crisp crust
• Maximum rise
• Beautiful texture

---

Step 17: Bake Uncovered

Remove the lid.

Reduce temperature to:

450°F (230°C)

Bake another:

20 minutes

until deeply golden brown.

---

What Makes a Great Crust?

A perfect sourdough crust should be:

• Crisp
• Deeply colored
• Slightly blistered

This indicates proper baking.

---

Step 18: Cool Completely

Transfer loaf to a cooling rack.

Allow to cool for:

At least 2 hours

before slicing.

---

Why Cooling Is Essential

Fresh bread continues cooking internally.

Cutting too soon can result in:

• Gummy texture
• Compressed crumb

Patience leads to the best results.
