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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make and shape the dough
In a bowl, mix the egg yolks, butter, sugar, flour, and baking powder until smooth.
Roll the dough thin and cut into desired shapes.
Bake and finish
Bake in the preheated oven until lightly golden.
Frost with thin icing or sprinkle with granulated sugar while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and bind the dough, helping it hold its shape while baking.
- Butter
- Adds fat for tenderness and a rich flavor in the baked cookies.
- Sugar
- Sweetens the dough and contributes to golden browning in the oven.
- Flour
- Provides the structure that holds the rolled and cut shapes together.
- Baking powder
- Releases gas during baking so the cakes rise slightly and stay light.
The step that matters
Bake until lightly golden. Sugar and proteins brown quickly at this temperature, so the cakes can go from pale to over-browned fast. Pulling them when only lightly golden keeps them tender and avoids a bitter, dry edge.
“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.
