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

What each ingredient does

Molasses
Provides the dark color, deep flavor, and sweetness, and keeps the candy moist.
Sugar
Adds sweetness and forms the crystalline structure that sets the candy when cooked.
Vinegar
Adds acidity that helps prevent sugar from crystallizing into a grainy texture.
Butter
Adds fat for richness and a tender bite.
Baking soda
Reacts with the acid in the syrup, releasing gas that lightens the texture.
Peanuts
Add crunch, nutty flavor, and fat to the set candy.

The step that matters

Boiling to the brittle stage. Sugar syrup sets according to how far its water has boiled off. Stopping early leaves the taffy sticky and soft, while cooking too long makes it hard, bitter, or burnt. Checking the brittle stage in water tells the cook when the syrup is ready.

Swap the peanut

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

  1. Almondfits better
  2. Pecansfits about as well
  3. Walnutfits about as well
  4. Peanutthe original

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