Ingredients
For the Dough
- 500g bread flour
- 100g active sourdough starter
- 250g whole milk, cold
- 50g granulated sugar
- 10g fine sea salt
- 50g unsalted butter, softened
- 1 large egg
For the Butter Block
- 250g unsalted European-style butter
For Egg Wash
- 1 large egg
- 1 tablespoon milk
Equipment Needed
- Stand mixer or mixing bowl
- Rolling pin
- Plastic wrap
- Bench scraper
- Loaf pan (9×5 inch)
- Pastry brush
- Kitchen scale
- Baking sheet
- Cooling rack
Step 1: Prepare the Dough
Time: 15 Minutes
Intensity: Easy
In a large mixing bowl combine:
- Bread flour
- Active sourdough starter
- Milk
- Sugar
- Egg
Mix until a rough dough forms.
Add:
- Salt
- Softened butter
Knead for 8–10 minutes until smooth and elastic.
The dough should feel soft but not sticky.
Shape into a ball and place in a lightly greased container.
Cover and allow to rest.
Step 2: Bulk Fermentation
Time: 4–6 Hours
Intensity: Easy
Let the dough ferment at room temperature until it expands by approximately 50%.
Perform one stretch and fold after 2 hours to strengthen gluten development.
The dough should become airy and elastic.
Once fermentation is complete, refrigerate for 1 hour.
Cold dough is easier to laminate.
Step 3: Make the Butter Block
Time: 15 Minutes
Intensity: Moderate
Place the butter between two sheets of parchment paper.
Using a rolling pin, flatten the butter into an 8-inch square.
Aim for even thickness throughout.
Refrigerate for 30 minutes.
The butter should remain cold but flexible.
If too hard, it may crack during rolling.
If too soft, it may leak into the dough.
Step 4: Enclose the Butter
Time: 15 Minutes
Intensity: Moderate
Roll the chilled dough into a 12-inch square.
Place the butter block diagonally in the center.
Fold the corners of the dough over the butter, sealing completely.
Pinch seams closed.
The butter should be fully enclosed inside the dough.
Step 5: First Lamination Fold
Time: 20 Minutes
Intensity: Advanced
Roll the dough into a rectangle approximately 8 x 24 inches.
Work gently to avoid tearing.
Fold the dough into thirds like a business letter.
This is known as a single fold.
Wrap and refrigerate for 45 minutes.
Step 6: Second Lamination Fold
Time: 20 Minutes
Intensity: Advanced
Rotate the dough 90 degrees.
Roll again into a long rectangle.
Fold into thirds.
This creates additional butter layers.
Wrap tightly.
Chill for another 45 minutes.
Step 7: Third Lamination Fold
Time: 20 Minutes
Intensity: Advanced
Repeat the rolling and folding process one final time.
After the third fold, refrigerate for at least 1 hour.
The dough should now contain hundreds of delicate layers.
Step 8: Shape the Loaf
Time: 20 Minutes
Intensity: Moderate
Roll the laminated dough into a rectangle measuring approximately 10 x 18 inches.
Starting from the short end, roll tightly into a log.
Place the log seam-side down into a greased loaf pan.
Cover loosely with plastic wrap.
Step 9: Final Proof
Time: 8–12 Hours
Intensity: Easy
Allow the loaf to proof overnight in the refrigerator.
Alternatively, proof at cool room temperature for 4–6 hours.
The loaf should become noticeably puffy and nearly double in size.
Proper proofing is essential for light, flaky layers.
Step 10: Prepare for Baking
Time: 10 Minutes
Intensity: Easy
Preheat the oven to:
375°F (190°C)
Mix the egg wash ingredients.
Brush the surface of the loaf gently.
Avoid pressing down on the delicate dough.
The egg wash helps create a shiny golden crust.
Step 11: Bake
Time: 40–45 Minutes
Intensity: Moderate
Bake the loaf in the center of the oven.
After 20 minutes, check the color.
If browning too quickly, tent loosely with foil.
The loaf is finished when:
- Deep golden brown
- Internal temperature reaches 200°F (93°C)
- Layers appear fully expanded
The kitchen will be filled with a rich buttery aroma.
Step 12: Cool
Time: 1 Hour
Intensity: Easy
Remove from the oven.
Allow the loaf to cool in the pan for 10 minutes.
Transfer to a cooling rack.
Cool completely before slicing.
Cutting too soon may compress the flaky layers.
Tips for Success
Use Strong Bread Flour
Higher protein flour creates better structure and supports lamination.
Maintain Proper Butter Temperature
The butter and dough should remain similar in firmness.
This prevents tearing and uneven layers.
Chill Between Folds
Resting the dough keeps the butter cold and preserves layer definition.
Avoid Excess Flour
Too much flour during rolling can toughen the final loaf.
Be Patient
Sourdough fermentation takes time but develops exceptional flavor.
