Sponge 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.

Prepare the batter

  1. Beat the eggs for 20 minutes.

  2. Stir in the sugar and flour.

  3. Beat the water and egg yolks together.

  4. Mix the mixture with the sugar.

Whip and fold

  1. Beat the egg whites to a froth.

  2. Fold the froth into the flour mixture, adding the cream of tartar with the last cup of flour.

Bake

  1. Bake in a moderate oven at 350°F (175°C) until done.

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

What each ingredient does

Eggs
Trap air when beaten, giving the cake its light, airy structure.
Flour
Forms the set crumb structure once the batter is baked.
Sugar
Adds sweetness and helps keep the beaten foam stable.
Cream of tartar
Acidifies the egg whites, helping the foam hold its volume and resist collapsing.

The step that matters

Folding the froth into the flour mixture. Folding gently keeps the air bubbles in the beaten egg whites. Those bubbles expand in the oven and give the cake its rise, so stirring or deflating the froth leads to a dense result.
