Strawberry Sponge

Ingredients

Directions

Make the custard

  1. Soak the gelatin in the cream.

  2. Heat the mixture in boiling water until the gelatin dissolves.

  3. Beat the egg yolks with the sugar, add the milk, and cook until thickened into a custard.

  4. Add the cream and gelatin mixture to the custard, then cool.

Add fruit and set

  1. Rub the strawberries through a sieve, add lemon juice, and stir into the cooling mixture.

  2. When the mixture begins to thicken, fold in the beaten egg whites until stiff.

  3. Pour the mixture into a mold and let it harden.

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

What each ingredient does

Gelatine
Sets the mixture so it holds its shape when cooled.
Egg yolks
Enrich and thicken the custard base.
Egg whites
Beaten until stiff, they add airy lightness to the set dessert.
Strawberries
Provide the main flavor and fruity moisture.
Cream
Adds richness and a smooth, creamy texture.

The step that matters

Folding in the beaten egg whites. If the mixture is too warm or too set, the whites deflate or fail to blend evenly; folding gently while the mixture just begins to thicken keeps the air and gives a light, uniform texture.

Swap the lemon

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Raspberryfits better
  4. Lemonthe original

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