Sunshine Sponge Cake

Oven, in the book's wordsA cool oven

Ingredients

Directions

The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Mix and sift the sugar and flour together four times.

Make the batter

  1. Beat the egg whites with the salt until frothy, then add the cream of tartar and beat until stiff and dry.

  2. Add the beaten egg yolks and vanilla, then beat again.

  3. Carefully fold in the flour and sugar mixture.

  4. Turn the batter into an ungreased mold lined with paper.

Bake

  1. Bake in a cool oven at 300°F (150°C) for 45 minutes to 1 hour.

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

What each ingredient does

Egg whites
Beaten into stiff foam, they give the cake its light, airy structure.
Egg yolks
Add richness and moisture and help the batter set into a tender crumb.
Flour
Provides the structure that holds the cake's airy foam once baked.
Sugar
Sweetens the cake and helps stabilize the whipped egg white foam.
Cream of tartar
Acidifies the egg whites, helping them whip to a stronger, more stable foam.

The step that matters

Carefully fold in the flour and sugar mixture. Folding gently preserves the air whipped into the egg whites. Stirring or deflating the batter at this point produces a dense, flat cake instead of a light sponge.

Swap the vanilla

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

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

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