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 ↓
Rich Puff Paste
Ingredients
Directions
Make the dough
In a bowl, combine the flour and butter, mixing until crumbly.
Add just enough water to form a stiff paste.
Laminate and fold
Roll out the dough and layer slices of butter on top.
Fold the ends in and roll thin; repeat this process twice.
Roll and fold the dough three to four times.
Variations
For a less rich paste, mix 1 pound of flour with ¼ pound of butter and enough water to form a paste with 1 beaten egg.
For a richer paste, combine 1 pound of dried flour, 6 ounces of butter, and 1 tablespoon of sugar, adding water to form a stiff paste.

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 gluten structure that holds the thin layers of dough together.
- Unsalted butter
- Forms separate fat layers that create flaky texture as the dough is rolled and folded.
- Egg
- Adds richness and structure to the paste in the less rich version.
- White sugar
- Adds sweetness and promotes browning in the richer version.
The step that matters
Layering the butter and folding. Butter must stay in distinct cold layers between dough sheets. If it softens and blends into the dough, the flaky layers are lost, so keep the dough and butter cool while rolling and folding.
