What each ingredient does

Brown sugar
Provides the sweetness and forms the set candy base as the syrup cooks.
Butter
Adds fat for richness and a softer, smoother bite in the finished taffy.
Vinegar
Adds acidity that helps keep the sugar from crystallizing into a grainy texture.

The step that matters

Cook over medium heat without stirring. Stirring while sugar syrup cooks can encourage sugar crystals to form, which makes the taffy grainy instead of smooth. Leaving the syrup undisturbed lets the sugar dissolve and cook evenly, and the vinegar helps guard against crystallization.
