White Sponge Cake

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a mixing bowl, beat the egg whites until stiff.

  2. Gradually add the sugar while continuing to beat until well combined.

  3. Gently fold in the flour and cream of tartar.

  4. Add flavoring to taste.

  5. Pour the batter into flat tins.

Bake and serve

  1. Bake until golden brown.

  2. If desired, ice with chocolate icing and cut into diamond shapes.

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 light, airy structure.
White sugar
Sweetens the cake and helps stabilize the whipped egg white foam.
Flour
Provides the set structure that holds the cake's airy crumb together as it bakes.
Cream of tartar
Acidifies the egg whites, helping them whip to a stronger, more stable foam.

The step that matters

Beat the egg whites until stiff. Under-whipped whites will not hold enough air, so the cake will be dense. Over-whipped whites turn dry and grainy and collapse, so fold gently after beating.
