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 hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
Wash the butter well and set aside 1 tablespoon.
Refrigerate the remaining butter.
Sift the salt with the flour and mix in the tablespoon of butter using your fingertips.
Add ice water to form a stiff dough and knead until smooth.
Laminate
Roll out into oblong pieces and place the remaining butter in the center.
Fold the sides and ends over the butter and let it stand for 10 minutes.
Roll out again with light, quick strokes.
Fold the ends to the center and then fold again.
Turn and roll as before, allowing it to rest between rollings.
After several rollings, cut into shape.
Shape and bake
Chill.
Bake in a hot oven (400°F / 200°C).
For rounds, cut ¼ inch thick.
Place two rounds together.
Cut out the center of the top with a smaller cutter.

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 gluten structure that holds the layers together as the pastry bakes.
- Butter
- Creates separate layers of fat that turn to steam in the oven, lifting the dough into flaky sheets.
- Ice water
- Keeps the dough cold and hydrated so the butter stays in solid pieces and the dough stays workable.
The step that matters
Keeping the butter and dough cold while rolling. If the butter softens and melts into the dough, the layers blend together and the pastry bakes dense instead of flaky. Chilling between rollings keeps the fat in distinct layers.
