Why it works: Butter and flour 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 warm oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat your oven to 400°F (200°C).
Rub the butter and sugar into the flour until well combined.
Mix in the egg yolks and orange‑flower water to form a paste.
Shape and bake
Roll out the paste very thin and cut into rounds using a cutter the size of a wine glass.
Butter some paper and place the rounds on it on iron plates.
Bake in the warm oven for a short time until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, helping the cakes stay short and crumbly.
- Flour
- Provides the structure that holds the thin rounds together while baking.
- Egg yolks
- Bind the dough and add richness and colour to the baked cakes.
- Lump sugar
- Sweetens the cakes and contributes to gentle browning in the oven.
The step that matters
Baking until lightly golden. The rounds are very thin and bake quickly, so they can dry out or darken too far if left too long. Watching for a light golden colour keeps them crisp but tender.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, flour, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
