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 ↓
Pie-crust
Ingredients
Directions
Sift the flour and mix in the salt.

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 crust as its proteins combine with water to build gluten.
- Butter
- Cut into the flour in pieces, it creates tenderness and flaky layers as it keeps the dough short.
The step that matters
Add cold water gradually. Too much water or overmixing develops gluten, which makes the crust tough. Adding water a little at a time and stopping once the dough holds together keeps it tender.
