Prune Whip

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.

Prepare the prunes

  1. Stew the prunes with sugar and lemon until soft.

  2. Remove the pits and mash the prunes.

Bake and serve

  1. Add the beaten egg whites and stir until light.

  2. Pour the mixture into a pan and bake at 350°F (175°C) for 20 minutes.

  3. Let it cool, then cover with sweetened whipped cream before serving.

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

What each ingredient does

Prunes
Provide the main body, moisture and fruity sweetness of the whip.
Eggs
Beaten whites trap air, giving the whip its light, airy texture and helping it set in the oven.
Sugar
Sweetens the prunes and balances their tartness.
Lemon
Adds acidity that brightens the flavour of the prunes.

The step that matters

Add the beaten egg whites and stir until light. Beaten egg whites hold air in a foam that gives the whip its lightness. Stirring too hard or too long deflates the foam, so the mixture bakes up dense instead of airy.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits about as well
  4. Lemonthe original

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