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).
Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Butter
- Forms separate layers in the dough that steam apart during baking, giving puff and flakiness.
- All-purpose flour
- Provides the structure that holds the layers of butter and dough together.
The step that matters
Keeping the butter in layers. If the butter softens or melts into the flour instead of staying in distinct sheets, the layers fuse and the pastry will not puff. Cool dough and gentle rolling keep the butter in separate layers.
