Apple Sponge

Ingredients

Directions

Prepare the gelatin and syrup

  1. Soak the gelatin in ¼ cup cold water for 30 minutes.

  2. Cook the sugar and boiling water together for 5 minutes.

Make the apple base

  1. Add the quartered, cored, and peeled apples, and simmer until tender.

  2. Stir in the dissolved gelatin.

  3. Press the mixture through a fine sieve.

  4. If the mixture is less than 2 cups, add water to make up the difference.

  5. Add the lemon juice and grated rind.

Set and serve

  1. Chill the mixture on ice, stirring occasionally until slightly thickened.

  2. Beat the mixture until foamy.

  3. Fold in the stiffly whisked egg whites.

  4. Pour the mixture into a mold.

  5. Refrigerate for 2 hours.

  6. Serve with cream or soft custard sauce.

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

What each ingredient does

Gelatin
Sets the mixture into a soft, sliceable structure as it cools.
Egg whites
Whipped into the mixture to lighten it and give a airy, sponge-like texture.
Apples
Provide the main fruit flavour and body of the sponge.
Sugar
Sweetens the mixture and balances the tartness of the apples and lemon.

The step that matters

Fold in the stiffly whisked egg whites. Egg whites hold air only when whisked stiff and must be folded gently so the foam is not deflated. Deflated whites produce a dense sponge instead of a light, airy set. The mixture should be thickened but not set before folding.

Swap the apple

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

  1. Vanillafits better
  2. Orangefits better
  3. Raspberryfits better
  4. Applethe original

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