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

What each ingredient does

Sugar
Forms the candy base and, when boiled to a crisp stage, sets hard and brittle as it cools.
Vinegar
Acidity helps keep the sugar from recrystallizing, giving a smoother, less grainy candy.
Butter
Adds fat that softens the candy's texture and gives it richer flavor.

The step that matters

Boiling without stirring. Stirring hot sugar syrup can trigger sugar crystals to form, making the candy grainy instead of smooth and glassy. Reaching the crisp stage by temperature or appearance matters, because undercooked syrup stays soft and overcooked syrup turns bitter and burnt.

Swap the peanut

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

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