French Puff-paste

Ingredients

Directions

Make the dough

  1. Chop half the butter into the flour.

  2. Stir the beaten egg yolk into the ice water and mix with the flour to form a stiff dough.

Laminate

  1. Roll out the dough thinly, baste with one-third of the remaining butter, fold closely, and roll out again.

  2. Repeat until all the butter is used up.

  3. Roll very thin and refrigerate the last folded roll for 10-15 minutes before shaping the crust.

Finish

  1. Wash with beaten egg while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the gluten network that gives the dough its structure and layers.
Butter
Separate fat layers create steam pockets during baking, producing flakiness.
Egg yolk
Adds richness and helps bind the dough and promote even browning.
Ice water
Keeps the dough cold and hydrates the flour without warming the butter.

The step that matters

Keeping the butter and dough cold while rolling. If the butter softens and blends into the dough, the separate layers are lost and the pastry bakes dense instead of flaky. Chilling between folds keeps the fat in distinct sheets.
