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

What each ingredient does

Molasses
Provides the main body, dark color and deep flavor of the taffy.
Sugar
Adds sweetness and, once boiled, helps the taffy set firm.
Vinegar
Dissolves the sugar and adds acidity that softens the texture of the candy.
Butter
Adds fat that makes the taffy tender and easier to pull.
Baking soda
Reacts with the acid in the vinegar and molasses, lightening the color and making the candy tender.

The step that matters

Boil until it hardens when dropped into water. Sugar candy sets according to how much water has boiled off. Too little boiling leaves the taffy sticky, while too much makes it brittle, so the drop test helps judge the right point.
