Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Make the dough
Chop half the butter into the flour.
Stir the beaten egg yolk into the ice water.
Work the flour into a stiff dough.
Laminate
Roll out the dough thinly.
Baste with one-third of the remaining butter.
Fold closely and roll out again, repeating until all butter is used.
Roll very thin and chill the last folded roll for 10-15 minutes.
Finish
Wash with beaten egg while hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough once worked with water.
- Butter
- Forms separate layers that steam and lift the pastry as it bakes.
- Egg yolk
- Adds richness and helps the pastry brown when washed on top.
- Ice water
- Keeps the dough cold and hydrates the flour without warming the butter.
The step that matters
Keeping the butter cold while folding and rolling. If the butter softens and melts into the dough, it will not form distinct layers, so the pastry loses its flaky rise. Chilling the folded roll helps keep the butter firm between turns.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
