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
Make the dough
Mix the butter into the flour until well combined.
Add enough ice water to form a hard dough.
Laminate
Roll out the dough on a floured surface and cover with bits of butter.
Roll the dough tightly like a jelly roll.
Cut the roll into three pieces and stack them with cut ends facing the sides.
Press down with a rolling pin and roll out again, keeping the layers intact.
Repeat the butter covering and rolling process two more times.
Chill and use
Chill the dough on ice until very cold before using.
When ready to use, press the rolls flat and roll out again, maintaining the layers.

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 structure of the dough once mixed with water.
- Butter
- Forms separate layers that create flakiness when the dough is rolled and baked.
- Ice water
- Hydrates the flour to form a dough while keeping the butter cold.
The step that matters
Keep the butter cold while laminating. If the butter softens and blends into the dough instead of staying in distinct layers, the pastry loses its flakiness. Chilling the dough until very cold keeps the butter firm between rolls.
