Ingredients

Directions

The book says “a sharp oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, whisk together the eggs and egg yolks with the sugar until light and fluffy.

  3. Gently fold in the sifted flour until just combined.

  4. Carefully stir in the melted butter.

  5. Divide the batter into greased ring molds placed on parchment paper.

Bake and assemble

  1. Bake in the preheated oven until golden and cooked through.

  2. Once cooled, spread jam on one layer and top with another.

  3. Cut into 8 pieces and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Provide structure and richness as they set during baking, holding the cake together.
Egg yolks
Add fat and richness, giving the cake a tender crumb and golden colour.
Sugar
Sweetens the cake and helps create a light, fluffy batter when whisked with the eggs.
Sifted flour
Forms the main structure of the cake as its proteins set during baking.
Melted butter
Adds fat for moistness and tenderness in the finished cake.
Jam
Adds sweetness and fruity flavour between the layers.

The step that matters

Fold in the flour gently. Overmixing after the flour goes in develops gluten and makes the cake tough, while gentle folding keeps the light, airy texture the whisked eggs and sugar created.
