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 gluten network that gives the dough its structure.
Lard
Coats flour particles to shorten gluten and create flaky layers.
Butter
Forms separate layers that puff into flakes as the dough bakes.
Cold water
Hydrates the flour to form a dough while keeping the fat firm.

The step that matters

Keeping the butter in distinct layers. If the butter softens and blends into the dough during rolling and folding, the layers merge and the pastry loses its flakiness. Keeping the dough cool and rolling gently preserves the separate fat layers that create flakes.
