Lemon Taffy

Ingredients

Directions

Make the taffy

  1. Put the sugar in a clean, bright pan.

  2. Dissolve the cream of tartar in vinegar and pour it over the sugar.

  3. Set the pan on the stove and boil gently.

  4. Test the mixture by dipping a little into cold water; it is done when it breaks off brittle.

Pull and flavor

  1. Pour the mixture onto buttered plates and pull it as soon as it is cool enough.

  2. Add the lemon extract while pulling.

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

What each ingredient does

White sugar
Forms the bulk of the candy and sets firm as the syrup cools.
Cream of tartar
Acid that helps prevent sugar from crystallizing, keeping the taffy smooth.
Vinegar
Acid that helps prevent sugar from crystallizing, keeping the taffy smooth.

The step that matters

Testing the mixture in cold water. Sugar syrup must reach the right concentration to set brittle. Too little boiling leaves taffy soft and sticky, while too much makes it hard and difficult to pull. A small cold-water test shows when it is ready.

Swap the lemon

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

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

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