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

What each ingredient does

Granulated sugar
Forms the candy's base structure and provides its sweetness and chewy body as it cooks.
Vinegar
Adds acidity that helps keep the sugar from crystallizing, giving the taffy a smoother texture.
Vanilla
Adds aroma and flavor to the finished taffy.

The step that matters

Cook without stirring until the mixture threads. Stirring can knock sugar crystals loose into the syrup, causing a grainy candy. The cooking stage determines the final firmness, so the syrup must be heated to the right point before it is removed from heat.

Swap the vanilla

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

  1. Vanillathe original
  2. Strawberryfits about as well
  3. Pineapplefits about as well
  4. Apricotfits about as well

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