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
Prepare the dough
Place the flour in a heap on a clean surface and make a well in the center.
Add half of the egg yolk into the well.
Add six drops of lemon juice.
Wrap the butter in a clean cloth and squeeze out the water.
Mix all ingredients together with your hands, adding water to achieve the consistency of the squeezed butter.
Flour a rolling pin and the surface to prevent sticking.
Roll out the paste to about ¼ inch thick.
Laminate and rest
Place the pat of squeezed butter on one half of the paste and fold the other half over it, pressing the edges together.
Let it rest on a plate in a cool place for 15 minutes.
Roll out the paste again and fold it into thirds.
Turn it so the rough edges face you.
Roll it out again and fold it into thirds.
Let it rest for another 15 minutes.
Repeat the rolling and folding process two more times, resting for 15 minutes each time.

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.
- Fresh butter
- Forms separate layers that puff apart when the pastry is baked.
- Egg yolk
- Adds richness and helps bind the dough together.
The step that matters
Keeping the butter cool and in a solid pat while folding. If the butter softens and blends into the dough, it will not form distinct layers, so the pastry will not puff. Resting the dough in a cool place between folds keeps the butter firm and the layers separate.

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