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 water and a pinch of salt until it resembles butter.
Let the dough rest for 30 minutes.
Laminate
Flatten the dough with your hand and place the butter on top.
Fold the dough over the butter from each corner and roll it out twice.
Let the dough rest in a cool place for 45 minutes.
Roll it out twice more, then let it rest for another 45 minutes.
Roll it out twice again.
Bake
Place the dough in a large paper bag that does not touch the paste.
Bake in a preheated oven at 400°F (200°C) for 20 minutes.

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.

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 gluten network that gives the pastry its structure and layers.
- Butter
- Forms separate layers between dough sheets, creating flakiness as it melts and steam lifts the layers.
The step that matters
Keeping the butter cold while rolling and resting. Cold butter stays in solid pieces between dough layers. If it softens and blends into the dough, the layers are lost and the pastry turns dense instead of flaky. Resting in a cool place keeps the butter firm between rolls.
