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
Prepare
In a large bowl, mix the flour, salt, and baking powder.
Add the lard and butter, and mix until crumbly.
Gradually add the ice water and mix until combined.
Shape
Roll out the dough, fold it over, and roll it out again several times to create flakiness.

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 main structure of the dough once it is mixed with liquid.
- Lard
- Coats flour particles so the dough stays tender and creates flaky layers when rolled.
- Butter
- Adds flavor and creates flaky layers as its water content turns to steam in the oven.
- Ice water
- Hydrates the flour to form dough while staying cold, keeping the fat solid for flakiness.
- Baking powder
- Releases gas that lightens the crust slightly, giving it a more tender texture.
The step that matters
Keeping the fat cold while mixing. If the lard and butter soften or melt into the flour, they blend in rather than staying as separate pieces. Those pieces later melt and create flaky layers, so cold fat and ice water matter.
