Sponge Cake-cocoanut

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.

Make the sponge

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

  2. In a bowl, combine the beaten eggs, cold water, sugar, baking powder, and enough flour to make a batter. Beat well and pour into jelly pans.

  3. Bake until golden and a toothpick comes out clean.

Make the cream

  1. For the cream, heat the milk almost to boiling.

  2. In a separate bowl, beat the eggs and mix with sugar and cornstarch combined with a little cold milk.

  3. Pour the egg mixture into the hot milk, stirring over heat until thick.

  4. Flavor with lemon or vanilla, then cool and spread between the cake layers.

Finish

  1. Cover the top with Royal icing.

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

What each ingredient does

Eggs
Provide structure and trap air in the batter, and thicken the cream when cooked.
Flour
Forms the batter's structure as the proteins set during baking.
Sugar
Sweetens the cake and helps keep it tender and moist.
Baking powder
Releases gas in the batter so the sponge rises in the oven.
Milk
Forms the base of the cream, giving it richness and body.
Cornstarch
Thickens the cream so it sets firm enough to spread between the layers.

The step that matters

Pour the egg mixture into the hot milk, stirring over heat until thick. Adding the egg mixture gradually while stirring keeps the eggs from scrambling. Cooking until thick lets the starch and egg proteins set into a smooth cream.

Swap the lemon

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