Sunshine Sponge Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

  1. Separate the eggs.

  2. Beat the egg whites until stiff.

  3. Gradually add the sugar to the egg whites while beating.

  4. In another bowl, beat the egg yolks and add the vinegar drop by drop, beating constantly.

  5. Simultaneously beat both the yolks and whites for three minutes.

  6. Gently mix the yolk and white mixtures together.

Add the flour and bake

  1. Sift the flour four times.

  2. Fold it into the mixture quickly.

  3. 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
Whipped whites and yolks trap air, giving the sponge its light, airy structure.
Granulated sugar
Stabilizes the whipped egg whites and adds sweetness and tenderness to the crumb.
Vinegar
Acidity helps stabilize the beaten egg foam, making it less likely to collapse.
Flour
Provides the set structure that holds the risen foam once baked.

The step that matters

Fold in the flour quickly. Folding gently and quickly keeps the air bubbles from the whipped eggs intact. Overmixing deflates the foam and produces a dense, tough cake.
