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 Pastry
Ingredients
Directions
Prepare the flakes
Weigh equal amounts of butter and flour.
Cut the butter into thin slices.
Take a little flour and roll it with a slice of butter into flakes.
Repeat until all butter and flour are combined.

Make the paste
Sprinkle water over the heap.
Mix into a smooth paste by hand.
Roll out the paste to ½ inch thick.
Divide the paste into four parts.
Fold and bake
Flour the board and roll each part as thin as a wafer.
Fold each rolled part over four times.
Use as needed.
Bake as soon as possible.

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 structure of the dough and absorbs the water and butter.
- Butter
- Creates separate layers that puff apart with steam, giving flakiness.
- Water
- Binds the flour and butter into a smooth, workable dough.
The step that matters
Keep the butter very firm. Cold, firm butter stays in distinct sheets between the dough layers. If it softens and blends into the flour, the layers merge and the pastry will not puff into flakes when baked.
