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 slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream together the butter and sugar until smooth.
Mix in the flour and add a little rose-water.
Shape and bake
Shape the mixture into small rounds and place them on a baking sheet.
Bake in a moderate oven at 350°F (175°C) 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 fat that makes the dough rich and tender.
- Sugar
- Sweetens and helps browning; creaming with butter traps air for a lighter crumb.
- Flour
- Provides the structure that holds the shaped rounds together.
The step that matters
Bake until lightly golden. The rounds are small and thin, so they can dry out and darken quickly. Baking only until lightly golden keeps them tender while the sugar and butter brown gently.
