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 melted butter, sugar, and tepid water.
Add baking powder and enough sifted flour to form a dough.
Roll out the dough very thin.
Cut with a round cake cutter.
Bake
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Melted butter
- Adds fat and richness, helping the cookies brown and turn tender.
- Sugar
- Adds sweetness and helps the cookies brown during baking.
- Baking powder
- Releases gas in the dough, helping the cookies rise and lighten.
- Sifted flour
- Provides the structure that holds the dough together and sets during baking.
The step that matters
Rolling the dough very thin. Thin dough bakes through and crisps evenly. Thick dough can stay doughy in the middle while the edges over-brown.
