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 ↓
Common Puff Paste
Ingredients
Directions
Prepare the butter
Soften the butter by placing it in a pot and submerging it in a deep pan of water overnight.
Make the paste
Mix half of the butter with the flour until combined.
Add just enough water to form a stiff paste, working it smooth.
Roll out the paste twice, then add the remaining butter in small lumps over the surface.
If it's hot, roll out the paste twice more, allowing time in between.
Dredge a little flour over the butter before folding the paste for rolling.
Handle the paste as little as possible to keep it light.
Roll out the paste three times, folding it lightly in between.
Bake
Set the prepared paste in the oven immediately for baking.

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
- All-purpose flour
- Forms the structure of the paste that holds the layers together.
- Unsalted butter
- Forms separate layers that steam apart in the oven, creating flakiness.
- Water
- Combines with the flour to form gluten, giving the paste its elastic structure.
The step that matters
Handle the paste as little as possible. Overworking develops gluten and warms the butter, which makes the paste tough and melts the layers before they can separate in the oven.
