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

What each ingredient does

Sugar
Forms the sweet candy base that sets as it cools and hardens.
Cream of tartar
Acidifies the syrup, helping prevent crystallisation for a smoother, less grainy candy.
Oil of peppermint
Provides the characteristic peppermint aroma and flavour.

The step that matters

Beat until the mixture whitens, then drop quickly. As the sugar syrup cools, it begins to crystallise and harden. Beating incorporates air and turns the mass opaque, so it must be dropped promptly before it sets in the pan or bowl.

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.
