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, mix the flour and butter lightly with your fingers until blended.
Add the baking powder and salt, then pour in the cold water and stir well.
Flour a mixing board, turn the mixture out onto it, and knead to form a light dough.
Shape the crust
Roll the dough out very thinly and line a pie tin with it.

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
- Provides the structure that holds the dough together and gives the crust its body.
- Unsalted butter
- Coats flour particles to keep the crust tender and creates flaky layers as it stays solid.
- Baking powder
- Releases gas that lightens the crust so it rises slightly rather than baking dense.
- Cold water
- Hydrates the flour so the dough binds, while staying cold keeps the butter from melting.
The step that matters
Keep the butter cold and handle the dough lightly. Solid pieces of butter melt in the oven and leave pockets that create flakiness. Overworking the dough develops gluten, making the crust tough rather than tender.
