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
Prepare the butter and cold tools
Wash the butter in cold water until it feels waxy, then divide it into three pieces and flatten them into thin cakes.
Drop the pats of butter into ice water.
Keep the rolling pin and board as cold as possible.
Dip your hands first in hot water, then in cold water.
Make the dough
Take one pat of butter, dry it on a cloth, and work it into the flour, keeping flour between your fingers.
Stir in ice water until about one-third of the flour is mixed, then repeat with the second and third portions of flour.
Press all the mixture lightly into a ball, then pat it down and roll it out to about ¼ inch thick.
Laminate and chill
Take a piece of butter from the ice water, dry it, and dredge a little flour on one side of the board.
Lay the butter on the floured side and roll it out.
Place the butter in the center of the paste, fold the sides over the butter, and then fold the ends over until they meet.
Double the folded paste again, then roll or pound it with the rolling pin until a long, thin strip is formed.
Lay on another piece of butter and repeat the folding and rolling process.
Place the finished paste in the refrigerator until thoroughly chilled.
Bake
Cut the chilled paste and bake.

Shared aroma: isobutyraldehyde (malty, green).
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 structure that holds the layers of butter and paste together.
- Butter
- Stays in separate layers that melt during baking, creating steam that lifts the pastry into flakes.
- Ice water
- Keeps the butter cold and helps bind the flour into a workable dough.
The step that matters
Keeping the butter and paste cold while folding. If the butter softens and blends into the dough instead of staying in distinct layers, the pastry loses its flaky rise. Keeping everything cold and chilling between folds keeps the layers separate.
