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
Place the flour on a clean surface.
Mix the flour with cold water to form a soft dough.
Laminate
Cut the butter into pieces and lay it on the flour.
Roll out the mixture into thin sheets, keeping the butter cold.
Roll out the dough thinly, place butter on it, and repeat until all butter is used.
Roll the dough tightly, then beat it with a rolling pin to incorporate the butter.
Fold the dough and roll it out three or four times.
The puff paste is now ready for use.

Shared aroma: isobutyraldehyde (malty, green).
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
- Unsalted butter
- Forms separate cold layers that turn to steam in the oven, lifting the dough into flaky puff.
- All-purpose flour
- Provides the structure that holds the thin dough layers together around the butter.
- Cold water
- Hydrates the flour so it forms a workable dough that can be rolled into sheets.
The step that matters
Keep the butter cold while rolling. If the butter softens and blends into the dough, it cannot form separate layers, so the pastry will not puff and rise flakily.
