Masterclass Flaky French Croissants

Step-by-Step Instructions

1. Make the dough (Day 1): In the bowl of a stand mixer fitted with a dough hook, combine the bread flour, sugar, yeast, salt, cold milk, cold water, and softened butter. Knead on low speed for 5-7 minutes until a smooth, slightly stiff dough forms. Turn the dough out, shape it into a flat rectangle, wrap it tightly in plastic wrap, and refrigerate overnight (8-12 hours). This slow, cold fermentation develops flavor and relaxes the gluten.
2. Create the butter block (Beurrage): Cut the 3 sticks of cold European butter into thick slabs. Arrange the slabs on a large piece of parchment paper to form a square. Place another piece of parchment on top. Using a heavy rolling pin, violently pound the butter to soften it slightly, then roll it out into a perfect, even 8x8-inch square. Trim the edges to make it exact, place the trimmings back on top, and roll flat. Wrap the square block and refrigerate for 30 minutes. The butter must be cold but pliable, bending without snapping.
3. Encase the butter (The Lock-in): On a lightly floured surface, roll the cold dough out into a 12x12-inch square. Place the 8x8-inch butter block diagonally in the center of the dough (like a diamond inside a square). Fold the four corners of the dough over the butter so they meet precisely in the center. Pinch all the seams tightly to completely seal the butter inside. You now have a dough-butter envelope.
4. The First Turn (Lamination): Lightly flour your surface and the dough. Using firm, even pressure, roll the dough out into a long rectangle, about 8x24 inches. Brush off any excess flour. Fold the dough in thirds, exactly like folding a business letter (bring the bottom third up, and the top third down over it). This is your first 'turn'. Wrap the dough tightly in plastic and refrigerate for 45 minutes to chill the butter and relax the gluten.
5. The Second and Third Turns: Remove the dough, place it on the counter with the open seam facing your right (like a book). Roll it out again into an 8x24-inch rectangle and fold it in thirds like a letter. This is turn two. Chill for 45 minutes. Repeat this entire process one final time for turn three. After the third turn, wrap the dough and refrigerate overnight (or at least 4 hours). You have now created 27 distinct layers of butter.
6. Roll and shape (Day 2): On a floured surface, gently roll the cold dough out into a massive, long rectangle, about 10x30 inches and 1/4-inch thick. Using a pizza cutter and a ruler, trim the edges to make a perfect rectangle. Cut the dough into long, sharp triangles (about 4 inches wide at the base). Take one triangle, gently stretch it slightly, cut a small 1/2-inch slit in the center of the base, and roll it up tightly from the base to the pointed tip. Place the shaped croissants on parchment-lined baking sheets, with the pointed tip tucked underneath.
7. The Proof (Crucial Step): Brush the croissants lightly with the egg wash. Let them proof in a draft-free place at a cool room temperature (ideally 75°F - any warmer and the butter will melt out) for 2 to 2.5 hours. They should double in size, become incredibly puffy, and you should visibly see the distinct layers separating on the sides. They should jiggle like gelatin when you shake the pan.
8. The Bake: Preheat oven to 400°F (200°C). Gently brush the proofed croissants with one more delicate coat of egg wash. Bake for 15-20 minutes until they are deeply, darkly golden brown all over. Do not underbake them, or the inside will be doughy instead of flaky. Transfer to a wire rack to cool completely. The crust will shatter loudly when you bite into it.
