Sunshine 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. Preheat the oven to 350°F (175°C).

  2. Beat the egg yolks until thick and set aside.

Make the batter

  1. In a separate bowl, add the pinch of salt and cream of tartar to the egg whites and beat until very stiff.

  2. Gradually add the sugar to the egg whites and beat thoroughly.

  3. Add the orange extract and the beaten yolks, then mix lightly.

  4. Carefully fold in the sifted flour.

Bake and cool

  1. Pour the batter into an ungreased cake pan and bake for 50 minutes.

  2. Invert the cake to cool.

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

What each ingredient does

Eggs
Whipped whites trap air, giving the sponge its light, airy structure.
Cream of tartar
Stabilises the whipped egg whites so they hold their volume longer.
Sugar
Sweetens the cake and helps stabilise the whipped egg whites.
All-purpose flour
Provides the set structure that holds the sponge once baked.
Orange extract
Adds the orange aroma and flavour to the cake.

The step that matters

Carefully fold in the sifted flour. Folding gently keeps the air beaten into the egg whites. Overmixing deflates the batter, so the sponge bakes up dense instead of light and airy.

Swap the orange

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Orangethe original

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