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 together the flour, powdered sugar, cream of tartar, and salt into a bowl.

Make the batter

  1. Beat the egg whites until stiff peaks form.

  2. Gently fold the egg whites into the flour mixture until well combined.

  3. Add lemon extract to the mixture and fold gently.

  4. Pour the batter into a round cake tin with a center opening.

Bake

  1. Bake carefully until the cake is golden and 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

Whites of 10 fresh eggs
Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
Flour
Provides the structure that holds the airy foam once it sets in the oven.
Powdered sugar
Sweetens the cake and dissolves easily into the whites, helping keep the foam stable.
Cream of tartar
Acidifies the egg whites, stabilizing the foam so it holds its peaks longer.

The step that matters

Folding the egg whites into the flour mixture. Folding gently preserves the air whipped into the egg whites. Stirring or deflating the foam makes the cake dense and flat instead of light.

Swap the lemon

How well each one fits the dish's main ingredients (flour, sugar, cream, egg):

  4. Lemonthe original

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