Sponge-cake Roll

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 400°F (200°C).

  2. Beat the egg whites and yolks separately.

  3. Combine the sugar and flour, then mix in the cream of tartar.

Make and bake the cake

  1. Add the dissolved baking soda to the mixture.

  2. Fold in the beaten egg whites gently.

  3. Pour the batter into a biscuit pan and bake quickly.

  4. Once baked, turn the cake out onto a damp cloth.

Roll

  1. Spread a layer of dressing over the surface and roll up the cake while warm.

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

What each ingredient does

Eggs
Beaten whites trap air that gives the sponge its light, open structure.
Flour
Provides structure, which sets as the cake bakes.
Sugar
Sweetens the cake and helps keep the crumb tender.
Cream of tartar
Acid that stabilises beaten egg whites and reacts with baking soda to help the cake rise.
Baking soda
Reacts with the acidic cream of tartar to release gas that lifts the batter.

The step that matters

Fold in the beaten egg whites gently. The whites hold the air that makes the sponge rise. Stirring vigorously deflates the foam, leaving a dense, flat cake that may crack when rolled.
