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 ↓
Fine Puff-paste
Ingredients
Directions
Prepare the dough
Mix flour, baking powder, and salt; sift again.
Rub lard into the flour until smooth.
Add ice water with beaten egg white to form a stiff dough.
Laminate
Roll out into a thin sheet, spread with ¼ of the butter, and sprinkle with flour.
Roll up tightly like a scroll, double the ends towards the center, flatten, and reroll.
Repeat with remaining butter until used up.
Chill
Place in a dish, cover with a cloth, and chill for at least 1 hour 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
- Butter
- Forms the separate layers that puff apart in the oven as steam is released.
- Lard
- Shortens the dough, keeping it tender by coating flour strands and limiting gluten development.
- Flour
- Provides the structure that holds the layers together when rolled and folded.
- Baking powder
- Releases gas that helps the dough rise and lighten.
- Egg white
- Adds protein that helps bind the dough and gives a glossy finish.
The step that matters
Keeping the butter and lard cold. Cold fat stays in solid pieces between dough layers. When it melts in the oven, steam separates the layers, so warm fat would blend in and stop the puffing.
