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

What each ingredient does

Sugar
Forms the syrup that hardens into a crisp, glossy coating on the nuts.
Cream of tartar
Acidifies the syrup, helping prevent sugar from crystallising.

The step that matters

Boil until the syrup begins to discolor (310°F). Sugar syrup changes quickly near this stage. Stopping at the right point gives a clear, brittle coating when cooled; boiling too long can scorch the sugar and turn it bitter.

Swap the nuts

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

  1. Almondfits better
  2. Pistachiofits better
  3. Chestnutfits better
  4. Nutsthe original

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