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 ↓
To Make Puff Paste
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift the flour into a bowl, and reserve a little of the sifted flour for rolling.
Add cold water gradually to the flour to form a stiff paste.
Knead the paste well, then roll the paste out several times.
Wash the salt from the butter, then divide the butter into four parts.
Laminate the butter
Place one part of the butter in small pieces on the paste, fold the paste up, and roll the paste out again.
Repeat with the remaining butter until fully incorporated, handling the paste lightly.
Bake
Bake in a moderate oven at 350°F (175°C) until it rises and is lightly colored.

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 stiff paste that gives the pastry its structure.
- Unsalted butter
- Forms separate layers that puff into flaky sheets when the pastry bakes.
- Cold water
- Hydrates the flour so it forms a dough that can be rolled and layered.
The step that matters
Repeat folding with the remaining butter until fully incorporated. Each fold and roll creates thin alternating layers of dough and butter. If the butter melts into the dough or is unevenly spread, the layers fuse and the pastry will not rise flaky.
