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

What each ingredient does

Granulated sugar
Forms the syrup that sets into the light, sweet, glossy body of the filling.
Egg whites
Whipped into a foam that gives the filling its airy, light structure.

The step that matters

Pouring the boiling syrup into the egg whites. Pour the hot syrup slowly while beating briskly. Pouring too fast or without stirring can cook the whites unevenly or deflate the foam, so the filling loses its airy texture.

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.
