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 the dough
Place flour on a clean surface.
Work in ¼ pound of butter lightly with your hands.
Add enough water to achieve the same consistency as the remaining butter.
Knead until smooth, then roll out to ½ inch thick.
Laminate
Place remaining butter, cut into slices, on half of the paste.
Dust lightly with flour and fold the paste over the butter.
Press down with a rolling pin and let it rest for a few minutes.
Roll out three times, making it thinner each time, resting between rolls.

Shared aroma: isobutyraldehyde (malty, green).
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
- Forms separate fat layers that create steam and lift between sheets of dough during baking.
- Flour
- Provides the structure of the dough, which holds the layers together when rolled.
- Water
- Combines with the flour to form the gluten network that gives the dough its elasticity.
The step that matters
Placing the remaining butter on the paste. If the butter is too warm or soft, it blends into the dough instead of forming distinct layers, which prevents the flaky rise. Keeping the butter cold and the dough resting between rolls helps maintain separate layers.
