Peach Sponge

Ingredients

Directions

Make the peach base

  1. Boil water and sugar together in a double boiler for 15 minutes.

  2. Pass enough peaches through a colander to make 1 pint of pulp.

  3. Add the pulp to the sugar mixture and boil for 10 minutes.

  4. Dissolve gelatin in ½ cup cold water; add to the mixture and remove from heat to cool.

Set and serve

  1. Beat the egg whites until nearly stiff in a bowl set in ice water.

  2. Fold the beaten egg whites into the mixture.

  3. Pour the mixture into a mould or individual moulds.

  4. Refrigerate until firm.

  5. Serve with cream and garnish with sliced peaches if desired.

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

What each ingredient does

Egg whites
Whipped to foam, they lighten the mixture and give the dessert its sponge-like airy texture.
Gelatine
Sets the liquid peach mixture into a firm, sliceable dessert as it cools in the fridge.
Peach pulp
Provides the main peach flavour, natural fruit sweetness and moisture to the dessert.
Sugar
Sweetens the mixture and helps form a syrup with the water and peach pulp.

The step that matters

Folding in the egg whites. Beaten egg whites hold air that gives the sponge its lightness. If the whites are over-beaten they become dry and grainy, and heavy stirring deflates them, so the mixture should be folded gently while it is still cool enough not to melt the foam.

Swap the peach

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

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Peachthe original

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