Why it works: Butter and flour 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 the dough
Divide the butter into four equal parts.
Divide three of those parts into two portions each.
Mix the first quarter of butter into the flour with a broad-bladed knife.
Do not use warm hands to avoid heavy dough.
Add a little cold water to moisten the mixture.
Mix quickly with the knife.
Build the layers
Sprinkle a marble slab with flour.
Roll out the dough into a sheet.
Cut one portion of butter into small bits.
Distribute the butter bits evenly over the dough.
Sprinkle the dough with flour.
Fold the dough to cover the butter.
Roll the dough out again.
Repeat the process until all butter is incorporated, rolling lightly.
Rest and shape
Let the dough cool for 10 minutes.
Arrange the dough in pie dishes.

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).
Butter and flour 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
- Butter
- Forms separate layers that puff into flaky texture when the dough is folded and rolled.
- All-purpose flour
- Provides the structure that holds the dough sheets and butter layers together.
- Cold water
- Moistens the flour so the dough comes together and can be rolled into sheets.
The step that matters
Keep the butter cold and rolling light. If the butter softens and blends into the dough instead of staying in distinct pieces, it cannot form separate layers, and the pastry will turn heavy rather than flaky. Warm hands and heavy rolling both push the butter into the dough.
