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, then dip them in hot and cold water.
Rinse a large bowl with boiling water, then with cold, and fill it half with cold water.
Wash the butter in the cold water until it is light and waxy.
Shape the butter into two thin cakes and chill in ice water.
Make the dough
Mix 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 a smooth ball forms.
Lightly flour a board and turn the pastry onto it.
Pound the pastry lightly with a rolling pin without breaking it.
Laminate and chill
Roll the pastry to about ¼ inch thick, then spread remaining butter in bits on top.
Sprinkle lightly with flour and fold the pastry from each side to meet in the middle.
Fold from the ends without having them meet, then double the pastry.
Pound lightly and roll to about ⅓ inch thick, repeating the folding and rolling process three times for pies.
Chill the rolled pastry in the ice for at least one hour before use.

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
- Pastry flour
- Forms the structure that the butter layers are folded into.
- Butter
- Creates separate layers that steam apart during baking, giving puff and flakiness.
- Ice water
- Keeps the butter cold and hydrates the flour to form a workable dough.
- Salt
- Seasons the dough and strengthens its gluten structure.
The step that matters
Keeping the butter cold while folding. If the butter softens and melts into the dough, the layers blend instead of separating, so the pastry bakes flat rather than puffing. Chilling between folds keeps the butter in distinct layers.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
