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

  1. Preheat the oven to 400°F (200°C).

  2. Beat the butter and sugar together until creamy.

  3. Add the all-purpose flour, rice flour, and baking powder, mixing until combined.

  4. Incorporate the egg and mix until smooth.

  5. Shape the mixture into smooth balls using your hands.

Bake and assemble

  1. Place the balls on a buttered baking sheet lined with parchment paper.

  2. Bake in the preheated oven until golden.

  3. Once cooled, stick two balls together with jam.

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.
