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

What each ingredient does

Dark brown sugar
Provides sweetness and the caramel flavor that defines the candy.
Milk
Adds moisture and dairy richness, dissolving the sugar into a syrup that can set.
Chopped nuts
Add crunch and toasty flavor to the set candy.

The step that matters

Judging the roping stage. Cooking must stop at the roping stage, when the syrup forms a thread that falls in a rope from a spoon. Undercooked candy stays soft and sticky, while overcooked candy turns hard and grainy as sugar crystallizes too far.

Swap the nuts

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

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

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