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

What each ingredient does

Sugar
Provides sweetness and, when boiled, sets into a hard, brittle candy as it cools.
Cream
Adds fat and richness, softening the sugar mixture's texture before it hardens.
Walnuts
Add crunch and nutty flavor to the candy.

The step that matters

Boiling until brittle. Hard candy sets only when the sugar syrup is cooked long enough that little water remains. Undercooked syrup stays soft or sticky and will not harden properly as it cools.

Swap the nuts

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

  1. Hazelnutfits better
  2. Cocoafits better
  3. Nutsthe original
  4. Almondfits about as well

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