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 the dough
Preheat the oven to 400°F (200°C).
Beat the butter and sugar together until creamy.
Add the all-purpose flour, rice flour, and baking powder, mixing until combined.
Incorporate the egg and mix until smooth.
Shape the mixture into smooth balls using your hands.
Bake and assemble
Place the balls on a buttered baking sheet lined with parchment paper.
Bake in the preheated oven until golden.
Once cooled, stick two balls together with jam.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cookies a tender, crumbly texture.
- All-purpose flour
- Provides the main structure that holds the dough together as it bakes.
- Rice flour
- Makes the cookies lighter and more delicate in texture than wheat flour alone.
- Egg
- Binds the dough and adds moisture and structure to the cookie.
- Baking powder
- Releases gas as it heats, helping the cookies rise slightly and stay light.
- Sugar
- Sweetens the dough and helps it brown as it bakes.
The step that matters
Bake until golden. Butter-rich dough spreads and browns quickly, so pulling the cookies once golden keeps them tender rather than dry or bitter from over-browning.
