Ingredients

Directions

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

Prepare

  1. Sift the flour and baking powder together.

  2. In a heatproof bowl, combine the eggs and sugar.

Make the batter

  1. Place the bowl over a saucepan of boiling water and whip for 20 minutes.

  2. Melt the butter and mix it lightly into the egg and sugar mixture.

  3. Stir in the flour quickly.

  4. Grease a cake tin and pour the mixture into it.

Bake

  1. Bake in a moderate oven (350°F / 175°C) for 45 minutes.

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

What each ingredient does

Eggs
Whipped with sugar to trap air, giving the sponge its light structure.
Sugar
Whipped with the eggs to stabilise the foam and add sweetness.
Flour
Provides the set structure once the batter is baked.
Baking powder
Releases gas in the oven, helping the batter rise.
Butter
Adds richness and a tender crumb to the sponge.

The step that matters

Stir in the flour quickly. Flour folded into a whipped egg foam can deflate it if overworked or left to stand. Gentle, quick folding keeps the air bubbles that give the sponge its lift.
