The flavor team

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

Flour
Forms the structure that holds the layers of dough together.
Butter
Forms separate layers that puff up as moisture turns to steam in the oven.
Lard
Keeps the dough tender and flaky by coating flour particles and limiting gluten development.
Ice water
Hydrates the flour while staying cold, keeping the fat solid so layers stay distinct.

The step that matters

Keeping the butter in tiny, separate pieces while rolling. If the butter softens or melts into the dough, it blends in instead of forming layers, so the pastry will not puff. Keeping the dough cold between folds keeps the fat solid and the layers intact.
