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 ↓
Puff Paste
Ingredients
Directions
Make the dough
Rub the flour into the butter until very fine.
Add cold water to form a light paste, just stiff enough to work.
Roll out the paste to about ¼ inch thick.
Laminate
Spread a layer of butter over the surface and sprinkle with a little flour.
Fold the paste, then roll it out again.
Repeat the folding and rolling process with layers of butter three times.

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
- All-purpose flour
- Forms the structure of the paste once mixed with water.
- Unsalted butter
- Forms separate layers that create flaky texture as the pastry is folded and rolled.
The step that matters
Rub the flour into the butter until very fine. If the butter is not worked fine enough, it forms uneven pockets rather than thin, even layers, which weakens the flaky rise. Keeping the mixture cool helps the butter stay solid until baking.
