Creah 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. In a bowl, beat the eggs until light and fluffy.

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

  3. In another bowl, mix the flour, cream of tartar, and baking soda.

  4. Combine the dry ingredients with the egg mixture, then fold in the sweet cream and lemon flavoring.

Bake

  1. Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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.
Flour
Forms the gluten network that gives the cake its set structure.
Sugar
Adds sweetness and helps stabilise the whipped eggs.
Sweet cream
Adds moisture and richness to the batter.
Cream of tartar
Acidifies the batter, stabilising foam and helping the leavening react.
Baking soda
Reacts with the acid in the batter to produce gas that helps the cake rise.

The step that matters

Folding in the sweet cream and lemon flavoring. Combining the dry ingredients with the egg mixture and then folding gently keeps the air trapped in the beaten eggs. Overmixing develops too much gluten and deflates the batter, leading to a dense cake.
