Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make and shape the dough

  1. In a bowl, combine the egg yolks, cream, butter, baking soda, and sugar.

  2. Mix until well combined, then add flour until the dough is manageable.

  3. Roll the dough very thin and cut into small cakes.

  4. Place half a blanched almond in the center of each cake.

Bake

  1. Bake in the preheated oven until lightly golden.

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 help bind the dough together.
Cream
Adds moisture and richness to the dough.
Butter
Adds fat that makes the cakes tender and rich.
Baking soda
Raises the dough's pH, helping it spread and brown.
Sugar
Adds sweetness and helps the cakes brown.
Flour
Provides structure so the dough can be rolled and cut.

The step that matters

Roll the dough very thin. Thin pieces bake through evenly and turn crisp, while thick pieces stay doughy inside and can brown unevenly before cooking through.
