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
Make the dough
Mix the flour with a lump of butter the size of an egg and the egg to form a stiff paste, adding cold water as needed.
Divide the butter into six equal parts.
Roll out the paste and spread one part of the butter on it, dusting with flour.
Repeat until all the butter is incorporated.
Rest and fold
Chill the paste in the refrigerator for 15-20 minutes.
Roll out the paste three times, each time in the opposite direction.
Chill again until cold before using.

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
- All-purpose flour
- Forms the gluten network that gives the dough its structure.
- Unsalted butter
- Forms separate layers that puff into flakiness when the dough is baked.
- Egg
- Binds the flour and adds richness and structure to the stiff paste.
The step that matters
Keeping the butter cold while rolling. If the butter softens and blends into the dough, it cannot form distinct layers, so the pastry will not puff. Chilling between rolls keeps the butter firm.
