Why it works: Butter and flour 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 into a bowl.
Make a well in the center of the flour.
Add the egg yolk and a little cold water.
Mix until the paste is the same consistency as butter.
Add lemon juice and more water if necessary to make the pastry light.
Knead the dough on a cold marble slab.
Laminate with butter
Roll the dough out.
Place the butter in the center of the dough.
Fold the paste over the butter.
Press the edges to seal.
Roll the dough out lengthwise.
Fold the dough into thirds.
Repeat this process three times.
Chill for 20 minutes between each set of rolls.
Chill for another 15 minutes after the third set.
Roll out the dough again three times.

Butter and flour 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
- Butter
- Forms separate layers in the dough that create flakiness as it bakes.
- All-purpose flour
- Provides the structure that holds the dough layers together.
- Egg yolk
- Adds richness and helps bind the paste.
- Lemon juice
- Adds acidity that helps keep the pastry light and tender.
The step that matters
Chilling between rolls. Cold butter must stay solid between folds. If the dough warms, the butter melts into the flour, and the separate layers that give puff pastry its rise are lost.

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