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, then roll, fold, and turn it 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 moderate oven at 350°F (175°C) 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 structure of the pastry as its starch and gluten set during baking.
- Butter
- Folded into layers in the dough, it creates flaky separation as it melts and steams during baking.
- Sugar
- Adds sweetness and helps the surface brown and caramelize in the oven.
- Egg
- Brushed on top, it gives the pastry a glossy, browned finish.
The step that matters
Folding and turning the dough with butter. The butter must stay in distinct cold layers within the dough. If it softens or blends in, the pastry loses its flaky layers, so keep the dough cool between turns.
