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
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the butter until free from salt.
Keep the flour and butter in a cold place along with all utensils.
Make the dough
Mix one-fourth of the butter into the flour, adding enough ice cold water to form a paste.
Roll out the dough thinly and spread more butter on it with a knife.
Fold the dough as you would a piece of paper, repeating until all the butter is incorporated.
Roll the dough thoroughly for better results, about half an hour.
Chill the dough in a cold place for several hours, preferably overnight, but do not freeze.
Bake
Bake in a moderate oven at 350°F (175°C).

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 dough that holds the thin layers together.
- Unsalted butter
- Solid fat layered through the dough, creating separate layers that puff apart as they bake.
- Ice cold water
- Combines with the flour to form the dough while keeping the butter firm and cold.
The step that matters
Keep the butter cold while rolling and folding. If the butter softens or melts into the dough, it blends in instead of staying in distinct layers. Cold, solid butter turns to steam in the oven and pushes the layers apart, so the pastry rises flaky.
