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

What each ingredient does

Sugar
Caramelizes to give the candy its sweet, browned flavour and firm body as it cooks.
Milk
Adds moisture and dairy solids that soften the caramel texture and mellow its colour.
Butter
Adds fat for smooth texture and rich flavour, helping the candy stay tender.
Nuts
Add crunch and a toasty flavour contrast to the soft, chewy candy.

The step that matters

Cook until the mixture hardens in water. Sugar syrup passes through set stages as its water boils off and its concentration rises. Stopping too early leaves a soft, sticky candy, while cooking too long makes it brittle or burnt, so the test must be checked carefully.

Swap the nuts

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

  1. Almondfits better
  2. Cocoafits better
  3. Pecansfits better
  4. Nutsthe original

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