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

What each ingredient does

Sugar
Forms the hard, glossy candy coating around the nuts as the syrup cools.
Cream of tartar
Acidifies the syrup, helping prevent crystallisation for a smooth, clear coating.
Nuts
Are the core that gets coated in the crisp sugar shell.

The step that matters

Cooking the syrup to hard-crack stage. The syrup must reach the hard-crack stage so the coating sets hard and brittle once cooled. Undercooked syrup stays sticky, while overcooked syrup can darken and taste bitter.

Swap the nuts

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

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

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