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 ↓
Soyer's Recipe for Puff-paste
Ingredients
Directions
Make the paste
Place the flour on a clean surface and make a hole in the center.
Add the egg yolk, lemon juice, and salt into the hole.
Mix with cold water to form a soft, flexible paste, handling it as little as possible.
Laminate the dough
Remove buttermilk from the butter and wring it in a cloth.
Roll out the paste.
Place the butter in the center of the paste.
Fold the edges over to cover the butter.
Roll out to ¼ inch thickness.
Fold one-third of the dough over.
Roll again.
Fold the other third over, forming a square.
Repeat the rolling and folding process twice more.
Place the paste on a floured baking sheet.
Chill for 30 minutes.
Roll twice more, turning as before.
Chill for another 15 minutes.
Give it two more rolls, making a total of seven.
Finish
The puff pastry is ready to use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the gluten network that gives the paste its structure and holds the layers together.
- Butter
- Forms separate solid layers that turn to steam in the oven, lifting the dough into flaky sheets.
- Egg yolk
- Adds richness and fat to the paste, tenderizing it and helping it brown.
- Cold water
- Hydrates the flour to form the dough while keeping the butter firm and separate.
The step that matters
Keeping the butter cold and the paste handled lightly. If the butter softens and blends into the dough, the layers merge and the pastry will not puff. Chilling between rolls keeps the fat solid, and minimal handling keeps the gluten from toughening the paste.
