White Sponge, or Angel 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

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

  2. Sift the cream of tartar into the flour five or six times and sift the sugar twice.

  3. Add a pinch of salt to the egg whites and whip them until very stiff.

Make the batter

  1. Gradually add the sugar to the whipped egg whites, beating it in from below.

  2. In the same manner, add the flour and then the vanilla extract, keeping the mixture light.

  3. Pour the batter into a perfectly bright ungreased pan or one lined with paper, preferably one with a tube in the center.

Bake and finish

  1. Bake for 30 to 40 minutes without moving or jarring the cake.

  2. Check for doneness with a broom straw before removing it from the oven; do not let it get too deeply colored.

  3. Let the cake stand in the pan for a few minutes, then loosen it around the sides to let it fall out.

  4. Turn the cake upside down and icing the bottom and sides if desired.

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 stiff foam that traps air and gives the cake its light, open structure.
Granulated sugar
Sweetens the cake and stabilizes the whipped egg white foam when beaten in gradually.
All-purpose flour
Provides the light structure that sets the cake as the egg white foam bakes.
Cream of tartar
Acidifies the egg whites, helping the foam stay stable and hold its volume.

The step that matters

Folding in the flour and vanilla while keeping the mixture light. Egg white foam is full of trapped air. Heavy mixing or deflating it removes that air, so the cake bakes dense and short. Gentle, careful folding keeps the batter airy so it rises well in the oven.

Swap the vanilla

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

  1. Raisinfits about as well
  2. Vanillathe original
  3. Figfits less well
  4. Strawberryfits less well

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