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

What each ingredient does

Lemon juice
Provides the sharp acidity that gives the ice its bright, tangy flavor.
Orange juice
Adds fruity flavor and a little extra sweetness to the lemon base.
Granulated sugar
Sweetens the ice and lowers its freezing point, keeping it softer and less icy.
Egg whites
Beaten whites add air and a light, smooth texture to the frozen ice.

The step that matters

Fold in the beaten egg whites just before freezing. Beaten whites trap air that gives the ice a light texture. If they sit too long they lose their foam and the mixture turns denser after freezing.

Swap the orange

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

  1. Orangethe original
  2. Vanillafits about as well
  3. Limefits less well
  4. Raisinfits less well

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