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, reserving a little for rolling.
Mix the flour with cold water to form a stiff paste and knead well.
Roll out the paste several times.
Laminate with butter
Wash the salt from the butter and divide it into four parts.
Place one part of the butter on the paste in small pieces and fold it up.
Roll the paste until the butter is well incorporated.
Repeat with the remaining butter portions.
Bake
Handle the paste lightly and bake in a moderate oven at 350°F (175°C) until it rises but does not brown.

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 gluten network that gives the paste its structure and stretch.
- Unsalted butter
- Forms separate layers within the dough that puff apart into flakiness when baked.
- Cold water
- Hydrates the flour to form the paste that is kneaded and rolled into layers.
The step that matters
Repeated rolling and folding of the butter. Butter must stay in distinct layers rather than blending into the dough. If the butter softens or the paste is overworked, the layers merge and the pastry loses its flaky rise when baked.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
