Directions

Prepare the apples

  2. Peel and core the apples, then rub the pulp through a sieve using a wooden spoon.

  2. In a separate bowl, beat the egg whites with orange water until frothy.

  3. Gradually mix the frothy egg whites into the apple mixture until well combined and light.

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

What each ingredient does

Apples
Provide the main pulp that gives the dessert its body and fruity flavour.
Egg whites
Whipped into foam, they lighten the apple mixture and give it an airy, fluffy texture.
Sugar
Sweetens the apple pulp and balances its natural tartness.
Rich boiled custard
Forms the creamy base layer beneath the light apple mixture.

The step that matters

Gradually mix the frothy egg whites into the apple mixture. Egg white foam is fragile. Adding it slowly and folding gently keeps air trapped inside, so the mixture stays light instead of deflating into a dense, runny layer.

Swap the currant

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

  1. Vanillafits better
  2. Pearfits better
  3. Figfits better
  4. Currantthe original

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