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 ↓
Common Pie Crust
Ingredients
Directions
Make the dough
Cut half of the butter into the flour, rubbing it in until fine.
Mix with a little cold water to form a stiff dough.
Fold and shape
Flour the board and roll the dough into a thin sheet.
Spread the remaining butter on the dough, fold, and roll it up.
Fold again into a scroll and divide into desired portions.
Roll out each portion to nearly an inch thick.

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
- Flour
- Forms the structure of the crust once mixed with water and fat.
- Butter
- Its fat creates separate layers that help the crust turn out flaky when baked.
- Cold water
- Hydrates the flour so the particles bind into a dough.
The step that matters
Folding the butter into the dough. Butter has to stay in distinct pieces and layers within the dough. If it softens and blends fully into the flour, the layers are lost and the crust becomes tender rather than flaky. Rolling and folding should be done with a light touch and without overworking the dough.
