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 the batter

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

  2. Beat the egg whites and yolks separately.

  3. Mix the sugar, flour, and cream of tartar together.

  4. Dissolve the baking soda in a little water and add it to the mixture.

  5. Fold in the beaten egg whites gently.

Bake and roll

  1. Pour the batter into a biscuit pan and bake until golden.

  2. Turn the cake out onto a damp towel and roll it up while warm.

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
Stabilizes the beaten egg whites so they hold their volume longer.
Baking soda
Reacts with the acid in the batter to release gas, helping the cake rise.
Flour
Provides the starch and protein that set during baking to form the cake's crumb.
Sugar
Adds sweetness and helps keep the sponge tender and moist.

The step that matters

Fold in the beaten egg whites gently. Folding keeps the air bubbles in the whipped whites intact. Stirring vigorously deflates the batter, leaving a dense, flat sponge that may crack when rolled.
