Chocolate 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 the oven to 350°F (175°C).

Make the batter

  1. Cream together the coconut, salt, and sugar.

  2. Add the beaten egg yolks, then the cold water.

  3. Sift the baking powder, cinnamon, and cocoa into the flour, then add to the mixture.

  4. Fold in the stiffly beaten egg whites.

Bake

  1. Pour the batter into muffin pans and bake for 20 minutes.

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

What each ingredient does

Eggs
Yolks enrich the batter, while whites trap air that lifts the cake and gives a light crumb.
Flour
Provides the starch and protein that form the cake's structure as it bakes.
Baking powder
Releases gas in the batter when heated, making the cake rise.
Cocoa
Adds chocolate flavour and a deep brown colour to the cake.
Sugar
Sweetens the cake, tenderises the crumb, and helps the crust brown.

The step that matters

Folding in the stiffly beaten egg whites. Egg whites hold the air that makes the cake light. Folding gently keeps that air in, while stirring or beating hard would deflate the batter and leave a dense cake.

Swap the cocoa

How well each one fits the dish's main ingredients (sugar, flour, egg, cinnamon):

  1. Almondfits better
  2. Chestnutfits better
  3. Milletfits better
  4. Cocoathe original

Fit is the average pairing score against sugar, flour, egg, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
