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 ↓
French Puff Paste
Ingredients
Directions
Make the dough
Sift the flour and rub in 2 ounces of butter.
Make a hole in the center and add egg yolks, salt, and half the water.
Knead quickly until smooth.
Laminate the dough
Roll out into a square ½ inch thick.
Place remaining butter on the paste and fold it over.
Roll out lightly, keeping the board floured.
Fold the paste in three and roll it again.
Repeat this process until it has had six turns.
If warm, cool it between rollings.

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 gluten structure that holds the paste together and gives the baked layers their framework.
- Butter
- Forms separate layers within the dough that puff apart into flaky sheets when baked.
- Egg yolks
- Add richness and fat to the dough, helping it stay smooth and tender.
- Cold water
- Hydrates the flour to form the dough while keeping it cool enough to hold its layers.
The step that matters
Keeping the dough and butter cold between turns. If the butter softens and melts into the dough, the layers blend together instead of separating, so the pastry will not puff properly. Cooling the paste between rollings keeps the butter in distinct sheets.
