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

What each ingredient does

Castor sugar
Forms the bulk of the mixture and sets firm as it dries, giving the creams their body and sweetness.
Egg white
Its proteins trap air when beaten, giving a light, frothy base that holds the sugar.

The step that matters

Adding the sugar gradually. Sugar added slowly to the beaten egg white lets the foam stay stable and absorb the sugar evenly. Adding it all at once can collapse the foam and leave a grainy, sticky mixture that will not roll out or firm up properly.

Swap the peppermint

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

  1. Cinnamonfits better
  2. Nutmegfits better

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