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
Prepare
Work quickly in a cool room to keep the pastry cold.
Flour a smooth surface.
Make the dough
Chop one-third of the butter into the flour with a sharp knife and add salt.
Mix in enough ice water to form a dough that doesn't stick to your hands.
Roll out the dough to about half an inch thick.
Laminate the butter
Cut the remaining butter into thick slices.
Lay the slices on the dough with one inch between them.
Dust flour lightly over the butter.
Fold the dough to completely enclose it.
Roll the dough to one inch thick.
Dust with flour.
Fold several times.
Roll out again.
Rest
Wrap the dough in a floured towel.
Chill for 15 minutes.

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 structure of the dough once mixed with water.
- Unsalted butter
- Creates flaky layers as pieces stay solid and steam during baking.
- Ice water
- Binds the flour into a dough while keeping the butter cold.
The step that matters
Keeping the butter cold. Cold butter stays in solid pieces that separate the dough into layers. As it bakes, the water in the butter turns to steam and lifts those layers. If the butter softens and blends into the flour, the pastry becomes dense instead of flaky.
