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. Sift the flour and baking powder together.

  2. Grease a cake tin and line it with paper.

Make the batter

  1. Combine the eggs and sugar in a basin.

  2. Place the basin over a pot of boiling water.

  3. Whip the mixture for 20 minutes.

  4. Melt the butter.

  5. Stir in the flour and melted butter, mixing lightly and quickly.

Bake

  1. Pour the mixture into the prepared tin and bake in a 350°F (175°C) oven for about 20 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 cake its light, airy structure.
Sugar
Adds sweetness and helps the whipped egg foam stay stable.
Flour
Forms the structure of the cake as its proteins set during baking.
Butter
Adds fat for a tender crumb and rich flavour.
Baking powder
Releases gas in the batter, helping the cake rise in the oven.

The step that matters

Whipping the eggs and sugar over boiling water. Warming the eggs and sugar lets them whip into a thick foam that holds air, which gives the cake its lift. Mixing the flour and butter in lightly and quickly keeps that air from collapsing.
