Why it works: Butter and flour 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
Choose a cool area in the kitchen to make the pastry.
Wash your hands in hot water to cool them before starting.
If no refrigerator is available, prepare a basin of ice in a cool part of the larder.
Make the dough
Mix the flour with a pinch of salt on a board.
Add a few drops of lemon juice and cold water to form a smooth paste, not too stiff.
Knead the paste until it is workable, then let it rest for about five minutes.
Squeeze the butter in a cloth to remove all liquid; it should be very cold.
Laminate
Shape the butter into a square and roll the paste out until it is thin.
Fold the paste over the butter in thirds, then roll it out again.
Repeat the rolling and folding process, ensuring to use flour as needed to prevent sticking.

Butter and flour 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
- Cold solid layers of fat that separate sheets of dough, creating flaky layers as it melts in the oven.
- Vienna flour
- Forms the gluten network that gives the dough its structure and elasticity for rolling.
- Cold water
- Hydrates the flour to form the dough, and keeping it cold keeps the butter from softening.
- Lemon juice
- Adds a little acidity that can help relax gluten, making the dough easier to roll.
The step that matters
Keeping the butter very cold. If the butter softens and blends into the dough instead of staying in separate layers, the pastry loses its flaky rise. Chilling between rolls helps keep it firm.
