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 ↓

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
- All-purpose flour
- Forms the structure of the dough when mixed with water.
- Lard or drippings
- Cut into the flour to create fat pockets that make the crust tender and flaky.
- Butter
- Adds flavor and fat layers that separate into flakes during folding and rolling.
- Ice water
- Hydrates the flour to bind the dough while keeping the fat solid.
The step that matters
Keeping the fat cold while laminating. Butter and lard must stay firm so they stay in separate layers. If they soften and blend into the dough, the layers are lost and the crust becomes less flaky. Chilling the dough between folds helps keep the fat solid.
