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

What each ingredient does

Light brown sugar
Provides sweetness and the bulk of the candy's chewy structure as it cooks.
Molasses
Adds deep flavour and extra moisture, giving the taffy a darker colour and softness.
Vinegar
Adds acidity that helps prevent sugar crystals from forming, keeping the taffy smooth.
Butter
Adds richness and fat, which tenderises the texture and softens the chew.

The step that matters

Boiling to the brittle stage. Sugar syrup must reach the correct concentration to set firm but not hard. Stopping too early leaves a sticky taffy, while overcooking makes it too hard and can scorch the sugars.

Swap the vanilla

How well each one fits the dish's main ingredients (sugar, molasses, vinegar, 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 sugar, molasses, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
