White 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. Sift the flour and powdered sugar together.

  2. Beat the sifted mixture into the stiff egg whites.

  3. Add a pinch of cream of tartar and the lemon juice just before baking.

Bake

  1. Pour the batter into three loaf pans.

  2. Bake in a moderate oven at 350°F (175°C) until done.

  3. For a variation, substitute the lemon juice with shredded coconut.

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, airy structure.
Flour
Provides the starch and gluten network that sets the cake's structure as it bakes.
Powdered sugar
Sweetens the cake and dissolves easily into the whites, helping keep the foam stable.
Cream of tartar
Stabilizes the whipped egg whites, helping the foam hold its volume.
Lemon juice
Adds acidity that brightens flavour and further helps stabilize the egg white foam.

The step that matters

Adding the cream of tartar and lemon juice just before baking. Acid stabilizes the whipped egg white foam, but it works best when added late. Waiting until just before baking keeps the foam from collapsing and deflating before the batter reaches the oven.

Swap the coconut

The recipe marks coconut as optional. How well each one fits the dish's main ingredients (sugar, egg, flour, lemon, cream):

  1. Raisinfits better
  2. Vanillafits better
  3. Raspberryfits better
  4. Coconutthe original

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