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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

Make the batter

  1. In a bowl, mix the flour, powdered sugar, and cream of tartar together.

  2. In a separate bowl, beat the egg whites until stiff peaks form.

  3. Gently fold the flour mixture into the beaten egg whites.

  4. Pour the batter into a greased loaf pan.

Bake

  1. Bake for about 30-35 minutes or until a toothpick comes out clean.

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

What each ingredient does

Egg whites
Whipped into a foam that traps air, giving the cake its light, airy structure.
Powdered sugar
Adds sweetness and dissolves finely, helping keep the foam smooth and stable.
Flour
Provides structure, setting the airy foam into a firm crumb as it bakes.
Cream of tartar
Acidifies the egg whites, stabilizing the foam so it holds its peaks longer.

The step that matters

Gently fold the flour mixture into the beaten egg whites. Egg white foam holds its air only while it is handled gently. Vigorous stirring knocks out air bubbles, which leads to a dense, flat cake.

Swap the lemon

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