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 ↓
Puff Paste
Ingredients
Directions
Prepare the dough
Sift and weigh the flour, then place it on a board or marble slab.
Sprinkle a little salt and sugar over the flour.
Beat the egg yolks and stir in a few spoonfuls of ice-cold water.
Pour the egg mixture slowly into the center of the flour while working it with your fingers.
Continue to work the mixture until you have a smooth and firm paste.
Add the butter
Work the butter until it is supple but not too soft.
Divide the butter into three equal parts.
Spread one part of the butter over half of the paste, then fold the other half over it.
Turn and chill
Roll out the paste, spread the second portion of butter, fold, and roll out again.
Repeat with the third portion of butter.
After three turns, chill the paste for 10-15 minutes before continuing with the last three turns.

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 paste that holds the layers of butter.
- Butter
- Forms separate layers that steam and puff the pastry as it bakes.
- Egg yolks
- Add richness and help bind the flour and water into a smooth dough.
The step that matters
Keeping the butter cold and workable during the turns. If the butter gets too warm or soft, it blends into the dough instead of forming distinct layers, so the pastry will not puff well. Chilling between turns keeps the butter firm enough to stay in sheets.
