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 ↓

Ingredients
Directions
Make the dough
In a bowl, combine the flour and half of the butter.
Add enough cold water to form a dough.
Roll the dough out thinly.
Laminate
Dot the remaining butter in small pieces over the dough and sprinkle with flour.
Roll the dough up, then roll it out again thinly.
Repeat the process with the remaining butter until all is used.
Rest
Keep the dough in a cool place until ready to 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
- All-purpose flour
- Forms the structure of the dough when combined with water.
- Unsalted butter
- Forms layers between sheets of dough, creating flakiness as it stays solid during rolling.
- Cold water
- Hydrates the flour so the dough holds together.
The step that matters
Keeping the butter cold while rolling. If the butter softens and blends into the dough, it cannot form separate layers, so the pastry loses its flaky rise. Keeping the dough cool between rolls keeps the butter in distinct pieces.
