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 ↓

Ingredients
Directions
Prepare the dough
Sift the flour.
Weigh the flour into an earthen bowl.
Sprinkle a little sugar and a pinch of salt over the flour.
Beat the egg yolks.
Add 3 teaspoons of ice water.
Stir the mixture into the flour using your fingertips.
Check if the mixture is too dry. Add more water to form a stiff dough.
Add the butter
Add ⅓ of the cold butter.
Work the butter into the dough until all water and salt are incorporated.
Spread the butter evenly on the dough.
Mix the dough thoroughly.
Chill the dough on ice for a while.
Repeat the butter addition process until all butter is used.
Chill and bake
Roll the dough.
Place the dough on a plate to chill until nearly frozen.
Cover the dough with crushed ice.
Let the dough sit for an hour.
Cut the dough into the desired shape.
Bake the cut pieces.

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 gluten network that gives the dough its structure.
- Cold butter
- Forms separate layers that puff into flaky texture when baked.
- Egg yolks
- Add richness and fat, helping the dough bind and brown.
- Ice water
- Hydrates the flour to form a cohesive dough while keeping the butter cold.
The step that matters
Keeping the butter cold while incorporating it. If the butter softens and blends into the dough instead of staying in distinct pieces, it will not form separate layers, so the pastry will not puff and flake properly. Chilling between additions helps keep the butter firm.
