Peach Sponge

Ingredients

Directions

Prepare the gelatine and syrup

  1. Soak the gelatine in 1/2 cup of water for 2 hours in a cool place, or 30 minutes on the back of the stove if in a hurry.

  2. Boil the remaining water and sugar together for 15 minutes.

  3. Mash the peaches finely and press them through a fine colander, then pour the syrup over them.

Make the sponge

  1. Place the saucepan with the mixture in another saucepan filled with boiling water and cook for 5 minutes, stirring constantly.

  2. Add the soaked gelatine and stir for another 5 minutes.

  3. Place the pan in cold water and stir until it begins to cool, then fold in the beaten egg whites.

  4. Continue stirring until the mixture starts to harden, then pour it into a mold and refrigerate.

Serve

  1. To serve, unmold the sponge and serve with cream and sugar.

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 unmolded.
Egg whites
Beaten into the mixture to give the sponge its light, airy texture.
Peaches
Provide fruit flavour and moisture to the sponge.
Sugar
Sweetens the syrup and the finished sponge.

The step that matters

Folding in the egg whites. The mixture must be cool and only just starting to thicken before the beaten egg whites are folded in. If it is too warm, the whites deflate and lose their airiness; if it sets too far, they will not blend in evenly.

Swap the peach

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

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

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