Type how much flour you have — the portion weight recalculates.
Classic French croissants on the Weekend Bakery formula, which credits Hamelman: a milk-and-water détrempe and a lamination butter block at 56% of the flour weight, folded three times over a multi-day cold schedule. Twenty-seven layers of butter, earned slowly.
How it works
The détrempe
Water 28% and milk 28%, sugar 11%, butter 8% in the dough itself, salt 2.4% and 2.2% instant yeast. Mix only until smooth — lamination will build all the structure; a strong-kneaded détrempe fights the rolling pin at every turn.
Lamination
The roll-in butter is 56% of the flour weight, beaten into a cold, plastic square. Lock it in, then give three letter folds with ~30 minutes of fridge rest between each — that yields the classic 27 butter layers. Cold discipline is the whole craft: if the butter smears warm or shatters cold, the layers are gone.
Shaping, proofing, baking
Roll out, cut long triangles (~80 g each), and roll from base to tip. Proof gently at 24–26 °C — warm enough to rise, cool enough that the butter stays put — until visibly jiggly, then bake around 200 °C convection until deep bronze and audibly crisp.
FAQ
Why does the schedule span days?
Every stage wants cold rests: the détrempe overnight, the folds between chills, often the shaped croissants overnight too. Compressing it warms the butter and merges layers — the published three-day rhythm exists because it is the one that works.
How much roll-in butter is standard?
The professional band is 50–56% of flour: Weekend Bakery at 56%, other respected French formulas at 50%. Below that you drift toward laminated brioche; the flake budget is the butter.
My croissants leaked butter in the oven?
Underproofed (layers rupture instead of rising) or proofed too warm (butter melted before the bake). The jiggle test and the 24–26 °C ceiling are the two guardrails.
