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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cut the butter into walnut-sized pieces and mix with the flour using a knife.
Add cold water as needed to form a dough.
Roll out the dough and place it in a cold place for 10 minutes.
Roll out the dough again and place it on buttered plates.
Layer and bake
Beat the egg and brush it on the edges of the dough to form the crust.
Layer three sheets of dough, wetting each layer with the egg.
Bake in a preheated oven at 400°F (200°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.

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
- Butter
- Creates solid pockets that melt during baking, separating layers so the pastry puffs and flakes.
- Flour
- Forms the structure of the dough that holds the layers together as the pastry bakes.
- Cold water
- Hydrates the flour so the dough comes together into a workable sheet.
- Egg
- Binds the layers and brushed on the edges, helping the crust seal and brown.
The step that matters
Keeping the butter cold while rolling. If the butter softens and blends into the dough, it cannot form separate layers, so the pastry bakes dense instead of flaky. Chilling the dough between rolls keeps the butter in distinct pieces.
“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.
