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

What each ingredient does

Sugar
Sweetens the filling and, boiled with water, forms the syrup that sets the egg whites.
Egg whites
Whipped with hot syrup to create a light, stable, marshmallow-like structure.

The step that matters

Pouring the hot syrup into the egg whites. The syrup must be hot and poured in a thin stream while beating briskly. This cooks the whites through and keeps them from scrambling or deflating, giving a stable, smooth filling.

Swap the lemon

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

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

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