Sponge Jelly 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. In a bowl, beat the eggs and sugar until light and fluffy.

  2. Sift together the flour, cream of tartar, and baking soda.

  3. Gently fold the dry ingredients into the egg mixture.

  4. Pour the batter into long cake tins.

Bake and roll

  1. Bake until golden brown.

  2. While warm, spread jelly on the cake and roll it up quickly.

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

What each ingredient does

Eggs
Beaten with sugar to trap air, giving the sponge its light structure.
Flour
Forms the cake's set structure once heated and held by the egg foam.
Cream of tartar
Stabilises the whipped egg foam and adds a slight acidity to the batter.
Baking soda
Reacts with the acidity in the batter to produce gas that helps the cake rise.
Sugar
Sweetens the cake and helps stabilise the beaten eggs into a fluffy foam.

The step that matters

Gently fold the dry ingredients into the egg mixture. Folding keeps the air trapped in the beaten eggs. Stirring vigorously knocks that air out, so the sponge bakes up flat and dense instead of light.
