Canada 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).

Make the batter

  1. Add the salt to the egg whites and beat them until stiff.

  2. Beat the yolks until light, then combine with the egg whites, beating vigorously.

  3. Add the sugar and beat thoroughly.

  4. Sift the flour and baking powder together twice, then gently fold into the egg mixture using a whisk or knife.

  5. Stir in the flavoring.

Bake

  1. Pour the batter into two well-buttered tins and bake for 30 minutes.

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

What each ingredient does

Eggs
Whites beaten to stiff peaks trap air, giving the cake its light, airy structure.
Sugar
Sweetens the cake and helps stabilise the beaten egg foam.
Flour
Forms the set crumb structure once the cake bakes.
Baking powder
Releases gas in the oven, helping the cake rise.

The step that matters

Folding in the flour. Flour must be folded in gently so the air beaten into the eggs is not knocked out. Deflated batter bakes up dense and flat.
