Winter 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 your oven to 350°F (175°C).

Make the batter

  1. In a mixing bowl, beat the eggs until frothy.

  2. Gradually add the sugar, continuing to beat until well combined.

  3. Sift in the flour and cream of tartar, mixing gently.

  4. Slowly add the boiling water and lemon flavoring, stirring until smooth.

Bake

  1. Pour the batter into a prepared 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
Whipped to trap air, giving the cake its light, airy structure.
Sugar
Sweetens the cake and helps stabilize the whipped egg foam.
All-purpose flour
Forms the structure that sets the cake as it bakes.
Cream of tartar
Stabilizes the egg foam and keeps the cake's texture fine and tender.
Boiling water
Adds moisture and helps the batter bake up soft.

The step that matters

Slowly add the boiling water. Pouring the water in slowly while stirring keeps the whipped egg foam from deflating. Adding it all at once or stirring hard can collapse the air the eggs have built, leaving a dense, flat sponge.

Swap the lemon
