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

What each ingredient does

Sour apples
Provide the grated fruit base and tartness that balances the sweetness.
Egg whites
Whipped into a foam that gives the dessert its light, airy structure.
Sugar
Sweetens the grated apples and softens their sharp acidity.

The step that matters

Beat the egg whites to a froth. Egg whites must be whipped until they hold a foam, since their proteins trap air and set the texture. Underbeaten whites stay runny and the float collapses, while overbeaten whites turn dry and grainy.

Swap the apple

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

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

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