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 and holds the layers together.
- Butter
- Forms separate solid layers that melt during baking, creating flakiness and lift.
- Ice water
- Keeps the dough cold and limits gluten development so the dough stays workable.
The step that matters
Keeping the butter cold while laminating. If the butter softens and blends into the dough, it will not form distinct layers, so the pastry loses its flaky rise. Chilling between folds keeps the butter solid.
