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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Sift the flour onto a clean surface and make a well in the center.
Gradually add 2 oz of warm butter, sugar, and cold water to the well.
Mix into a dough and let it rest in a cool place for 15 minutes.
Roll out the dough into a strip and place the remaining butter in the center.
Fold the pastry over the butter. Roll the pastry. Fold the pastry. Turn the pastry.
Repeat the fold‑roll‑fold‑turn sequence five times.
Shape and bake
Roll the pastry to about ½ inch thick and cut into rounds with a scalloped cutter.
Place on a baking sheet, brush with egg, dust with sugar, and mark with a knife in diamond patterns.
Bake in a 350°F (175°C) oven for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the pastry its structure.
- Butter
- Forms separate layers that turn to steam in the oven, lifting the pastry.
- Egg
- Brushed on top, it promotes browning and a glossy finish.
- Sugar
- Adds sweetness and helps the top brown in the oven.
The step that matters
Keeping the butter layers distinct during folding. If the butter softens or melts into the dough, the layers blend together and the pastry will not rise into flaky sheets. Keeping the dough and butter cool between folds preserves the separate layers that create lift.
“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.
