Genoese Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Prepare

  1. Line a cake tin with buttered paper.

Make the batter

  1. In a basin, combine the eggs and caster sugar, then place over a pan of hot water and whisk until creamy.

  2. Melt the butter and gently stir it into the egg mixture, alternating with the flour.

  3. Pour the batter into the prepared cake tin.

Bake

  1. Bake for 50 minutes in a moderate oven at 350°F (175°C).

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.
Castor sugar
Sweetens the cake and helps whisk the eggs into a stable, creamy foam.
Butter
Adds richness and tenderness, and carries flavor through the crumb.
Flour
Provides the starch and gluten network that sets the cake's structure as it bakes.

The step that matters

Whisking the eggs and sugar over hot water. Gentle warmth helps the sugar dissolve and the eggs foam more readily, producing more volume. Overheating can scramble the eggs, so the water should stay hot, not boiling, and the mixture should be whisked until thick and creamy.
