White 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

  1. Preheat the oven to 350°F (175°C).

  2. Sift the flour and cream of tartar together.

Make the batter

  1. Beat the egg whites until stiff.

  2. Gently stir the sugar into the beaten egg whites.

  3. Add the flour mixture, stirring as little as possible.

  4. Flavor with bitter almond extract.

Bake

  1. Pour the batter into a loaf pan and bake until golden.

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

What each ingredient does

Egg whites
Whipped into foam that gives the cake its airy structure.
Sugar
Sweetens the cake and helps stabilize the whipped egg white foam.
Flour
Provides the starch and structure that sets the cake's crumb as it bakes.
Cream of tartar
Acidifies the egg whites, helping them whip to a stable, stiff foam.

The step that matters

Add the flour mixture, stirring as little as possible.. Over-stirring knocks air out of the whipped egg white foam and develops gluten in the flour, making the cake dense and tough instead of light.
