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

What each ingredient does

Sugar
Forms the sweet base that sets into the chewy taffy texture as it cooks.
Vinegar
Acidity helps keep the sugar from crystallizing into grainy pieces.
Butter
Adds fat for a softer, richer bite in the finished taffy.

The step that matters

Cooking to the hard ball stage. Sugar syrup sets according to its final temperature, which rises as water boils off. Cooking too little leaves a sticky taffy, while cooking too long makes it brittle. Medium heat gives more control over this point.

Swap the walnut

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

  1. Almondfits better
  2. Sesamefits better
  3. Soybeanfits about as well
  4. Walnutthe original

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