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
Make the dough
Mix the flour with the egg yolk, cold water, and salt lightly with your fingertips until moderately firm.
Place the mixture on a clean surface.
Put the butter, pressed in a cloth to remove milk, in the center.
Fold the paste over the butter.
Set aside on ice for 15 minutes.
Laminate
Dredge flour over the paste.
Dredge flour under the paste.
Roll it out to about ½ inch thick.
Keep it square at both ends.
Fold the paste in thirds.
Roll it out again in the opposite direction.
Repeat the folding process.
Repeat the rolling process.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Forms the gluten structure that holds the dough together and gives it strength to roll.
- Unsalted butter
- Forms the separate fat layers that steam and lift the pastry during baking.
- Egg yolk
- Adds richness and helps bind the dough.
- Cold water
- Hydrates the flour to form the dough while keeping the fat firm.
The step that matters
Keep the butter in a cold, separate layer. If the butter softens or blends into the dough, the layers fuse and the pastry will not puff. Chilling between rolling and folding keeps the fat solid so it creates distinct layers that steam apart in the oven.
