Imperial Genoise Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Whisk eggs and sugar in a kettle set in warm water.

  2. Pour in melted butter, then add ground almonds and flour, and mix until well combined.

Bake

  1. Bake in shallow molds or in sheets at 350°F (175°C) until golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Eggs
Whisked with sugar to trap air, giving the cake its light, airy structure.
Sugar
Whisked with the eggs to stabilise the foam and add sweetness and tender texture.
Butter
Adds richness and moisture, and softens the crumb.
Flour
Provides the structure that holds the cake together as it sets.
Ground almonds
Add moisture, tenderness and nutty flavour to the crumb.

The step that matters

Whisking the eggs and sugar. The batter's rise depends on the air whisked into the eggs and sugar. Warming the mixture helps the eggs foam more readily and hold that volume. Folding the other ingredients in gently preserves the trapped air.
