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
Sift the flour onto a pastry board and make a well in the center.
Add the salt, lemon juice, and cold water.
Knead the mixture thoroughly and roll it into an oblong strip.
Laminate
Knead the butter in a cloth to remove moisture and shape it into a flat cake.
Place the butter in the center of the paste, wet the edges with cold water, and fold over to enclose the butter.
Roll it out carefully, fold it into thirds, and roll it out again; repeat this 4-5 times, resting the paste in a cool place for 15 minutes between each turn.
Allow the paste to stand for at least 30 minutes before using.

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.
- Butter
- Forms separate layers that create flakiness when the dough is rolled and folded.
- Cold water
- Hydrates the flour to form the dough while keeping the butter firm.
The step that matters
Keeping the butter and paste cold during folding. If the butter softens and blends into the dough, it will not form distinct layers, so the pastry loses its flakiness. Resting the paste between turns keeps the fat firm and the layers separate.

Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
