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 ↓
Soyer's Recipe for Puff Paste
Ingredients
Directions
Make the dough
On a clean surface, make a mound with the flour and create a well in the center.
Add the egg yolk, lemon juice, and salt into the well.
Gradually mix in cold water to form a soft, flexible paste, handling it as little as possible.
Laminate the dough
Remove butter from the refrigerator, wrap it in a cloth, and roll out the paste.
Place the butter in the center of the paste and fold the edges over to cover it.
Roll out the paste to a thickness of ¼ inch.
Fold the paste into thirds, rolling it out again after each fold to form a square.
Flour a baking sheet and place the paste on it, then chill for 30 minutes.
Roll out the paste twice more, turning it as before, and chill for another 15 minutes.
Roll out the paste two more times, making a total of seven rolls, and it is ready to use.

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 gluten network that gives the paste its structure and shape.
- Fresh butter
- Forms separate layers that puff into flaky sheets when the water in it turns to steam.
- Cold water
- Hydrates the flour into a dough that can be rolled while keeping the butter layers distinct.
- Egg yolk
- Adds richness and tenderness to the paste.
The step that matters
Keep the butter cold and the paste handled lightly. If the butter softens and blends into the dough, the layers are lost and the pastry will not puff. Overworking the paste develops gluten, making it tough and hard to roll. Chilling between folds keeps the butter firm and the layers distinct.
Swap the lemon

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