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

What each ingredient does

White sugar
Provides sweetness and, when boiled, hardens into a brittle, chewy candy structure.
Molasses
Adds deep flavor and moisture, and helps the candy set firm and chewy.
Chocolate
Contributes rich flavor and color to the caramel.
Chopped nuts
Add crunch and texture throughout the set candy.

The step that matters

Boil until brittle when tested. Sugar candy sets by concentration. Boiling removes water until the syrup reaches the hard-crack stage; stopping early leaves a soft, sticky result, while overcooking can scorch the sugars and taste bitter.

Swap the walnut

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

  1. Almondfits better
  2. Peanutfits better
  3. Pistachiofits about as well
  4. Walnutthe original

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