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
Make the dough
Mix flour, baking powder, and salt in a large bowl.
Sift the mixture again.
Cut the cold butter and lard into the flour until it forms a very fine, smooth paste.
Add enough ice water mixed with the beaten egg white to form a stiff dough.
Laminate
Roll out the dough into a thin sheet.
Spread ¼ cup of butter and sprinkle with a little flour.
Roll the dough tightly into a scroll shape, folding the ends toward the center.
Flatten and reroll.
Repeat the rolling and buttering process until all the butter is used.
Rest
Place the dough on a dish, cover with a cloth, and refrigerate for at least an 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
- Flour
- Forms the main structure of the dough once mixed with liquid.
- Cold butter
- Creates flaky layers as it stays in pieces and melts during baking, separating the dough sheets.
- Cold lard
- Keeps layers distinct and tender by staying solid until the dough is baked.
- Baking powder
- Releases gas during baking to help the layers rise and lighten.
- Egg white
- Adds binding and structure to the dough as it is mixed with the ice water.
The step that matters
Keeping the butter and lard cold during lamination. If the fat softens and blends into the flour, it will not stay in separate layers, so the pastry loses its flakiness. Keeping fats cold and chilling the dough between rolls keeps the layers distinct for lift in the oven.
