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

What each ingredient does

Granulated sugar
Provides the sweet base and forms the crystalline structure of the mints.
Gum arabic
Acts as a stabilizer that keeps the sugar from crystallizing too coarsely.
Cream of tartar
Adds acidity that helps prevent sugar from crystallizing and keeps the texture smooth.
Water
Dissolves the sugar so it can be boiled into a syrup.

The step that matters

Boil until it forms a ball in water. Boiling to the correct sugar concentration determines the final texture. Too little cooking leaves the mints soft and sticky, while overcooking makes them hard and brittle.

Swap the peppermint

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

  1. Nutmegfits better
  2. Cinnamonfits better
  3. Gingerfits about as well
  4. Peppermintthe original

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