Croissantthe lamination, in full

The lamination, in full: a four-ingredient dough, a sheet of cold butter trapped inside it, rolled and folded until the two are stacked a few hundred layers deep, then baked until the butter steams the pastry into a honeycomb. It is the site's most temperature-disciplined page — the whole craft is a narrow window, a few degrees wide, between the butter cracking and the butter melting. The dough itself is the simplest on the list (flour, water, a pinch of sugar, a little yeast); everything after that is the sequence, and the sequence is the recipe.

Prep

Cook

15 min

Total

~1 day, most of it resting

Equipment

• Rice paper (parchment), for the butter's rests and the final shape
• A long, thin rolling pin, 60 cm — the pin does the work, not the shoulders
• Two baking sheets, for the shaped croissants and for the final proof (one can go in the fridge)

Ingredients

• The dough — 500 g strong wheat flour · 250 ml cool water · 250 ml cool milk · 21 g fresh yeast (or 7 g instant) · 20 g caster sugar · 10 g fine sea salt
• The butter — 250 g plain butter, cold but workable (the temperature window, checked with your palm, before it goes anywhere near the dough)
• The finish — 1 egg plus 60 ml milk, beaten for the wash (or the brown butter route: a spoon of melted, lightly browned butter in place of the wash — a deeper colour and a toasty note)

Method

1. The dough. Mix the flour, water, milk, yeast, sugar and salt into a smooth, non-sticky mass. This is the dough step, done quickly — the gluten builds a little, but it's going to be rested and folded a dozen times, so there's no need to build it now. Wrap it in film, rest at room temperature 30 min.
2. Chill the butter. Press the 250 g of butter into a rough square between two sheets of rice-paper, then wrap tightly and put it in the fridge. It should be cold, and it should not be rock-hard: the goal is a square that gives to the thumb but holds its shape. This is the temperature gate — if it's too firm, it will break against the dough; if it's too soft, it will melt into it.
3. First fold. Roll the dough into a rectangle about twice the butter's width. Unwrap the butter, place it square on the dough, and fold the dough up over it — two thirds of the bottom edge up, then two thirds of the top edge down over the middle, sealing the seam. Press lightly. The butter is now trapped inside. Wrap and rest at room temperature 30 min.
4. Letter fold (three more times). Roll the whole rectangle out into a long strip, and fold it into thirds like a letter — bottom third to the middle, top third over it. Press gently, seal, wrap. 30 min rest. Repeat two more times, rolling out, folding to thirds, resting. After each fold the dough should be smoother and more pliable, and the butter should be moving with it, not against it. If the butter is starting to leak through the dough, put the whole thing in the fridge for 20 min before the next fold.
5. Rest. After the final letter fold, wrap and refrigerate for 1 h — the dough must be cold enough to roll cleanly and stay cold when you cut the triangles.
6. Shape. Roll out into a long strip about 3 mm thick. Cut off the short ends (they don't hold a shape). Cut the strip into long triangles, base about 8 cm, length about 20 cm. With the tip of a knife, make a shallow cut at the base of each triangle, perpendicular to the base. Roll each triangle up from the base to the tip, curving the tip under so the two short ends tuck beneath the centre — that's the crescent curve. Place, seam-side down, on the rice-paper-lined sheet, with room between them.
7. Final proof. Cover loosely and refrigerate overnight, or proof at room temperature for 1.5–2 h until the croissants have visibly puffed and the layers show. The final proof is the last thing the dough asks of the yeast before the oven does its steam.
8. Bake. Brush with the beaten egg-and- milk wash. A preheated oven at 200 °C / 400 °F, middle rack, 12–15 min, until deep golden and the layers have visibly separated. Rest on a rack 10 min — the butter is hot inside and will set the crumb as it cools; cutting early lets the steam out and collapses the honeycomb.

Common failures

Variations

• Almond. The same lamination, the same shape — and the almond filling (almond paste, a little sugar, a little milk (about 2 tbsp), beaten to a cream) goes into the slice after the bake, so the lamination isn't disturbed. The cream logic holds it; only the filling differs.
• The kouign-amann. The same butter, a denser dough, rolled and folded with a 200 g scatter of sugar at each fold, and baked dark. The brown butter note reads through the whole pastry.
• The filled croissant. The same lamination, the butter square in the dough as usual, and a 100 g filling (cream cheese, jam, or a quiche batter for a savoury version) pressed into the centre of each triangle before the roll.
