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 the oven to 350°F (175°C).

Make the batter

  1. In a large bowl, beat the egg whites until soft peaks form.

  2. Add the cream of tartar and continue beating until stiff peaks form.

  3. Gradually fold in the powdered sugar and flour until just combined.

  4. Pour the batter into an ungreased cake pan.

Bake

  1. Bake for 25-30 minutes or until a toothpick inserted comes out clean.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 traps air, giving the cake its light, airy structure.
Cream of tartar
Stabilizes the whipped egg whites so the foam holds its shape longer.
Flour
Provides the protein and starch that set during baking to form the cake's crumb.
Powdered sugar
Sweetens the batter and helps keep the whipped foam fine and stable.

The step that matters

Folding in the powdered sugar and flour. Folding gently keeps the air bubbles in the whipped egg whites intact. Overmixing deflates the foam, leading to a dense, flat cake.
