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

What each ingredient does

Lemon water ice
Provides the base flavor and the icy, frozen texture of the dish.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice softer.
Egg white
Coagulates during boiling and carries impurities to the surface so the syrup can be clarified.
Ginger
Adds a warm, aromatic spice flavor that infuses the frozen base.

The step that matters

Boil the sugar with egg white. Boiling makes the egg white coagulate and trap impurities, which rise to the surface where they can be skimmed off, giving a clear syrup.

Swap the ginger

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Dillfits about as well
  4. Gingerthe original

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