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

What each ingredient does

Sugar
Forms the bulk of the taffy and sets firm as the mixture cooks down.
Molasses
Adds dark color, deep flavor, and chewiness to the taffy.
Vinegar
Adds acidity that helps prevent sugar from crystallizing into a grainy texture.
Baking soda
Reacts with the hot syrup to create gas bubbles that lighten the texture.

The step that matters

Cook to the hardness test. Cooking the syrup to the right point controls how firm the finished taffy becomes. Stop too early and it stays sticky; go too far and it turns brittle.
