Laminating Dough: The Patience Behind Croissants

Those hundreds of flaky layers come from one simple idea repeated with cold butter and a calm hand.
Lamination is the process of folding a block of butter into dough again and again, building thin alternating sheets of fat and flour. In the oven the butter releases steam, pushing the layers apart into the airy, shattering crumb of a proper croissant. There is no special ingredient, only geometry and temperature.
The enemy is heat. If the butter warms and melts into the dough, the layers merge and you get bread instead of pastry. Work in a cool kitchen, chill the dough between folds, and move quickly when it is out of the fridge. If butter starts breaking through, stop and chill before you continue.
It is a project, not a weeknight task, and that is the point. Spread it across an evening and a morning, respect the rests, and you will pull trays of glossy, honeycombed croissants from your own oven. Few things in baking reward patience so directly.
