  3. Test the mixture in cold water; it should begin to thicken.

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

What each ingredient does

Light brown sugar
Provides the sweetness and the caramel-like flavor of the candy base.
Butter
Adds fat for a smoother, richer texture and a rounder flavor.
Vinegar
Adds a little acidity that helps keep the sugar syrup from turning grainy.

The step that matters

Boiling to the right stage. Boiling for about 20 minutes sets how much water leaves the syrup. Too little boiling leaves it soft and sticky, while too much makes it hard and brittle. The cold-water test helps judge when the syrup is thick enough to set as intended.

Swap the lemon

The recipe marks lemon as optional. 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.
