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

What each ingredient does

Sugar
Provides the sweetness and forms the firm, chewy body of the candy as it cooks.
Butter
Adds fat that softens the texture and gives the taffy a smoother bite.
Vinegar
Adds acidity that helps prevent sugar from crystallising into a grainy texture.
Lemon flavoring
Adds the lemon aroma and taste that defines the candy.

The step that matters

Continue cooking until the mixture reaches the hard ball stage. The sugar concentration set by cooking determines the final texture. Stopping early leaves the taffy soft and sticky, while cooking too long makes it hard and brittle.

Swap the lemon

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Apricotfits better
  4. Lemonthe original

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