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 for Pies
Ingredients
Directions
Prepare
Wash your hands with soap and water, then dip them in hot and cold water.
Rinse a large bowl with boiling water, then with cold water, and fill it halfway with cold water.
Wash the butter in the cold water until it is light and waxy, then shape it into two thin cakes and chill in ice water.
Make the dough
Mix the salt and sugar with the flour.
Rub one-third of the butter into the flour with your hands.
Add the ice water and stir quickly with a knife until the mixture forms a smooth ball.
Lightly flour a board and turn the paste onto it, pounding it gently with a rolling pin.
Roll the paste out to about ¼ inch thick, then spread the remaining butter in bits on top and sprinkle lightly with flour.
Fold and chill
Fold the paste in thirds from each side so the edges meet, then fold from the ends without having them meet.
Double the paste, pound lightly, and roll it out to about ⅓ inch thick.
Repeat the folding and rolling process three times for pies, or six times for other pastries.
Chill the rolled paste in the ice for at least one 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
- All-purpose flour
- Provides the structure that holds the layers of dough together.
- Unsalted butter
- Forms separate layers that steam and puff apart in the oven, giving flakiness.
- Ice water
- Keeps the dough cold and hydrates the flour so it forms a workable paste without melting the butter.
- Salt
- Adds flavor and strengthens the dough's gluten structure.
- Sugar
- Adds a little sweetness and helps browning in the oven.
The step that matters
Keeping the butter cold while folding. If the butter softens or melts into the dough, it blends into the flour instead of forming separate layers, so the pastry loses its flakiness and puff. Keeping the dough cold between folds preserves those layers.
