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

What each ingredient does

Sugar
Provides sweetness and, as the syrup cooks, sets into a firm, chewy candy structure.
Butter
Adds fat that softens the chew and gives the taffy a rich, tender texture.
Molasses
Adds deep flavor, dark color, and some moisture to the candy.
Vinegar
Adds acidity that helps prevent the sugar from crystallizing into a grainy texture.
Vanilla
Adds aroma that rounds out the sweet, caramel-like flavor.

The step that matters

Cook the syrup for the full 6 to 8 minutes. Sugar syrup becomes firmer as more water evaporates and its concentration rises. Cooking too briefly leaves the taffy soft and sticky, while cooking too long makes it hard and brittle.

Swap the vanilla

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

  1. Vanillathe original
  2. Figfits about as well
  3. Raisinfits about as well
  4. Applefits about as well

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