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 the batter

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

  2. In a bowl, beat the egg yolks thoroughly.

  3. Gradually add the sugar to the yolks, mixing well.

  4. Stir in the lemon juice and grated lemon rind.

  5. In a separate bowl, beat the egg whites until stiff peaks form.

  6. Gently cut and fold the egg whites into the yolk mixture.

  7. When nearly blended, add half of the flour and fold in gently.

  8. Add the remaining flour and fold until just combined.

Bake

  1. Pour the batter into a prepared cake pan.

  2. Bake for 20 minutes or until the cake is elastic to the touch.

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 and give the sponge its light, airy structure.
Pastry flour
Provides the gluten-based structure that holds the sponge once it sets.
Granulated sugar
Sweetens the cake and helps stabilise the yolks and whipped foam.
Lemon juice
Adds acidity that brightens the flavour of the cake.
Lemon rind
Adds aromatic lemon oils that give the cake its fragrance.

The step that matters

Fold the egg whites into the yolk mixture. Folding gently keeps the air in the whipped whites. Stirring or deflating them makes the sponge dense and flat instead of light.

Swap the lemon

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