Equipment Needed

• Ruler or measuring tape

• Pizza cutter or large chef’s knife

• Baking sheets lined with parchment paper

• Pastry brush

• Plastic wrap

• Stand mixer with a dough hook attachment (optional, can be kneaded by hand)

Ingredients

For the Dough (Détrempe):

• 500g Unbleached All-Purpose or Bread Flour (plus extra for dusting)

• 140ml Cold Water

• 140ml Cold Whole Milk

• 55g Granulated Sugar

• 10g Fine Sea Salt

• 10g Instant Yeast (or 12g Active Dry Yeast)

• 40g Unsalted Butter, softened at room temperature

For the Butter Block (Beurrage):

• 280g High-Quality European-style Unsalted Butter (at least 82% butterfat), chilled

For the Egg Wash:

• 1 Large Egg

• 1 tbsp Whole Milk or Heavy Cream

• Pinch of fine sea salt

Step-by-Step Instructions

Step 1: Prepare the Dough (Détrempe)

1. In the bowl of a stand mixer fitted with a dough hook, combine the flour, sugar, sea salt, and instant yeast.

2. Pour in the cold water, cold milk, and 40g of softened butter.

3. Mix on low speed for 3 minutes until the ingredients combine into a rough dough, then increase to medium-low speed for 4–5 minutes. The dough should be smooth but firm—avoid over-kneading to prevent excessive gluten development.

4. Shape the dough into a rough rectangle, wrap it tightly in plastic wrap, and chill in the refrigerator for at least 2 hours (or overnight for optimal flavor).

Step 2: Construct the Butter Block (Beurrage)

1. Cut the 280g of chilled European butter into even slabs.

2. Arrange the slabs on a sheet of parchment paper inside a pre-drawn 7×7-inch (18×18 cm) square outline.

3. Fold the parchment paper over the butter to enclose it securely in a 7×7-inch envelope.

4. Using a rolling pin, pound and roll the butter evenly until it fills the parchment square completely into a smooth, uniform block.

5. Chill the butter block in the refrigerator for 20 minutes. Note: The dough and butter must be at similar, pliable temperatures before laminating (approx. 50°F / 10°C).

Step 3: Lamination (Enclosing the Butter & Folding)

1. Roll out your chilled dough on a lightly floured surface into a rectangle measuring 7×14 inches (18×36 cm).

2. Place the cold butter block in the center of the dough sheet. Fold the two outer edges of the dough over the butter block, meeting in the middle. Pinch the center and top/bottom seams tightly to seal the butter inside completely.

Turn 1 (Single / Envelope Fold):

• Roll the dough carefully from the center outwards into a long rectangle measuring 8×24 inches (20×60 cm). Maintain straight edges and square corners.

• Fold the bottom one-third of the dough up toward the middle, then fold the top one-third down over it (like a business letter).

• Cover tightly with plastic wrap and chill in the refrigerator for 30 to 45 minutes.

Turn 2 (Single Fold):

• Rotate the dough 90 degrees so the open seam resembles a book spine facing your left.

• Roll out again to 8×24 inches, then perform another single envelope fold.

• Wrap tightly and chill for another 30 to 45 minutes.

Turn 3 (Final Single Fold):

• Repeat the rolling and folding process one final time (totaling 3 single folds).

• Wrap the dough tightly and rest in the refrigerator for at least 4 to 12 hours.

Step 4: Shaping the Croissants

1. Roll the chilled laminated dough out on a lightly floured surface into a long, thin rectangle measuring approximately 10×26 inches (25×65 cm) with a thickness of roughly 4mm.

2. Trim the rough edges neatly using a pizza cutter or chef’s knife to expose the delicate laminated layers.

3. Along the top and bottom edges, mark every 4.5 inches (11 cm). Cut diagonal lines connecting the marks to create 12 tall triangles.

4. Make a tiny 1/2-inch vertical notch in the center of each triangle’s base.

5. Gently stretch a triangle lengthwise, then start rolling tightly from the notched base up to the tip. Ensure the tip rests tucked underneath the bottom of the rolled croissant to prevent unrolling while baking.

6. Arrange the shaped croissants evenly across two parchment-lined baking sheets, leaving ample space between them.

Step 5: Proofing

1. Whisk together the egg, milk, and pinch of salt. Gently brush a thin layer of egg wash over each croissant, taking care not to let it drip onto the cut layered edges (which seals the layers shut).

2. Proof the croissants in a draft-free space at 75°F–78°F (24°C–25°C) for 2 to 2.5 hours. Crucial: Do not let the temperature exceed 80°F (27°C), or the butter layers will melt prematurely.

3. The croissants are ready when they have doubled in size, feel light and pillowy when gently nudged, and show visible layered ridges.

Step 6: Baking

1. Preheat your oven to 400°F (200°C) (or 375°F / 190°C convection).

2. Apply a second gentle coat of egg wash right before baking.

3. Place the baking sheets in the oven and immediately turn the temperature down to 375°F (190°C). Bake for 18 to 22 minutes until deep golden brown on top and firm to the touch.

4. Transfer to a wire cooling rack and allow to cool for at least 20–30 minutes before serving.

Pro-Tips for Success

• Keep Temperature Control Top-of-Mind: If the butter gets too warm, it melts into the dough, ruining the layers. If it gets too cold, it breaks into fragments during rolling. If the dough snaps or butter cracks, let it sit at room temperature for 3–5 minutes before rolling.

• Flour Sparingly: Always brush off excess flour before making every fold; excess flour creates dry streaks between layers.
