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 ↓

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 that holds the pastry together when baked.
- Butter or fat
- Coats flour particles and creates tenderness and flaky layers as it stays in pieces.
- Sugar
- Adds a little sweetness and helps the pastry brown.
- Ice water
- Provides the moisture that binds the dough while keeping the fat cold and firm.
The step that matters
Cut in the butter or fat until coarse crumbs. Fat should stay in small, cold pieces. Overworking it blends the fat into the flour, which makes the pastry tough instead of tender and flaky.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
