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
In a bowl, mix the flour with half of the butter until very fine.
Add enough cold water to form a stiff dough.
Laminate
Roll out the dough into a thin sheet.
Spread one-third of the remaining butter on the sheet.
Fold the dough into a long roll and re-roll it.
Repeat spreading and folding until all the butter is used.
Work quickly to keep the butter cold.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Forms the dough structure that holds the layers together as it is rolled.
- Butter
- Stays solid between dough layers, creating steam pockets that separate and lift the layers when baked.
- Cold water
- Hydrates the flour so it forms a stiff, workable dough.
The step that matters
Keep the butter cold while folding. If the butter softens and melts into the dough, it blends in instead of staying as separate layers, so the pastry loses its flakiness and rise.
