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 ↓

Directions
Make the dough
Mix half of the flour with a quarter of the butter and the ice water using a knife.
Flour a clean surface and turn out the dough.
Dredge it with flour and roll it thin.

Repeat rolling with the remaining butter and flour until all is used.

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
- All-purpose flour
- Forms the gluten network that gives the dough its structure and holds the layers together.
- Unsalted butter
- Stays solid between dough layers, then turns to steam in the oven, pushing the layers apart for flakiness.
The step that matters
Keep the butter and dough cold while rolling and folding. If the butter softens or melts into the dough, it merges with the flour instead of forming separate layers, and the pastry loses its flakiness. Minimizing hand contact and chilling the dough help keep the butter firm.
