Sponge Cake

Ingredients

Directions

Prepare

  1. Take 9 eggs.

  2. Weigh 8 eggs into granulated sugar and 4 eggs into flour.

  3. Grate rind of half a lemon and measure a tablespoonful of juice.

  4. Place sugar in a deep bowl, break the eggs, separate the whites, and beat the whites to a stiff froth.

  5. While breaking the eggs, chop each yolk into the sugar, stirring constantly until very fine and light.

Make the batter

  1. Add the grated lemon rind and then the juice.

  2. Add the beaten whites, cutting through and beating lightly, and then add the flour lightly.

Bake and serve

  1. Grease two pans, pour the batter into them, and bake in a moderately hot oven until a double broom whisk can be run through the centre of the cake and removed entirely dry.

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

What each ingredient does

Eggs
Whipped whites give the sponge its light, airy structure, and yolks add richness and colour.
Sugar
Sweetens the batter and helps stabilise the beaten egg foam.
Flour
Provides the starch that sets the cake's structure as it bakes.
Lemon juice
Adds acidity and brightness that lift the flavour of the sponge.

The step that matters

Folding in the beaten whites. Whites hold air only while stiff, so they should be cut through gently and lightly with the flour added softly. Overbeating or heavy stirring deflates the foam, leaving a dense cake.

Swap the lemon

Fit is the average pairing score against sugar, butter, milk, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
