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
Prepare the dough
Sift flour onto a clean surface.
Make a well in the center.
Add 3 ounces of butter, salt, and water into the well. Mix until smooth.
Laminate
Place another 3 ounces of butter in the center. Fold the dough over the butter.
Roll out the dough to a thin sheet. Fold the dough into thirds. Roll it out again.
Repeat this process twice, resting for 6-7 minutes between each rolling. Flour the surface as needed.

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 dough its structure.
- Butter
- Stays in separate layers during rolling, creating flakiness as it melts and steam lifts the dough.
- Water
- Hydrates the flour so gluten can form and bind the dough together.
The step that matters
Keeping the butter layer cold and intact while rolling. If the butter softens or breaks through the dough, it blends into the layers instead of separating them, so the pastry loses its flaky rise. Resting between rolls lets the gluten relax and keeps the butter firm.
