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 ↓
French Puff Paste
Ingredients
Directions
Make the paste
Sift the flour onto a board and make a well in the center.
Mix the flour into a paste with a small piece of butter, salt, lemon juice, and cold water.
Roll out the paste into a long strip.
Enclose the butter
Knead the remaining butter in a cloth to remove moisture and form it into a flat cake.
Place the butter in the center of the paste.
Wet the edges of the paste and fold over the paste to enclose the butter completely.
Turn, rest and use
Roll out the dough, then fold the dough in thirds.
Roll out the dough into an oblong shape again.
Repeat steps 8-10 four or five times, resting the paste in a cool place for 20 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 structure of the dough when mixed with water and rolled.
- Butter
- Forms separate fat layers that help create a flaky, layered texture.
- Cold water
- Hydrates the flour to form a workable dough while keeping the butter firm.
The step that matters
Keeping the butter and dough cold between turns. If the butter softens and melts into the dough, the layers blend together instead of staying separate, so the pastry loses its flakiness. Resting the dough in a cool place keeps the butter firm enough to hold its layers through each roll and fold.
