Velvet 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.

Prepare

  1. Sift the flour and sugar together five times.

Make the batter

  1. Whip the egg whites to stiff peaks, adding the cream of tartar when partially beaten.

  2. Gradually beat in the sugar, then add the egg yolks and mix well.

  3. Gently fold in the sifted flour and add vanilla extract.

Bake

  1. Pour the batter into an unbuttered pan and bake at 350°F (175°C) for 45 minutes.

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

What each ingredient does

Egg whites
Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
Cream of tartar
Stabilises the whipped egg whites, helping the foam hold its shape.
Egg yolks
Add richness, moisture and tenderness to the crumb.
All-purpose flour
Provides the starch that sets the structure of the cake as it bakes.
Granulated sugar
Sweetens the cake and helps stabilise the whipped egg white foam.

The step that matters

Gently fold in the sifted flour. Folding rather than stirring keeps the air bubbles in the whipped egg whites intact. Overmixing deflates the foam, leading to a dense, flat cake.

Swap the vanilla

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

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

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