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

What each ingredient does

Sugar
Forms the sweet base that cooks into a syrup and then sets into a soft, creamy fondant.
Cream of tartar
Acidifies the syrup, helping prevent sugar crystals from forming a grainy texture.

The step that matters

Beating the cooled syrup into fondant. The syrup must cool slightly before beating. Beating while it is too hot yields large sugar crystals, while beating it too cool can make it hard to work. Careful cooling and beating produce a smooth, soft cream.

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.
