Velvet Sponge Cake

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).

Make the batter

  1. In a large bowl, beat the eggs and sugar together until well combined.

  2. Add the flour, cream of tartar, and baking soda, and mix until smooth.

  3. Stir in the boiling water and lemon zest.

Bake

  1. Pour the batter into a pan and bake in the preheated oven.

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

What each ingredient does

Eggs
Provide structure and lift through whipped air and proteins that set during baking.
Sugar
Sweetens the cake and helps stabilise the beaten eggs.
Flour
Forms the crumb structure as its proteins and starches set in the oven.
Cream of tartar
Acidifies the batter, stabilising the egg foam and helping the leavening react.
Baking soda
Reacts with the acidic cream of tartar to release gas that makes the cake rise.

The step that matters

Stir in the boiling water and lemon zest. Boiling water must be added gently at the end so the batter stays aerated; overmixing after it goes in can knock out air and make the cake dense.

Swap the lemon
