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

What each ingredient does

Sugar
Provides most of the sweetness and, as it concentrates, the firm set of the candy.
Molasses
Adds deep flavor, dark color and sweetness, and gives the candy its chewy body.
Vinegar
Its acid partly breaks down sugar, which keeps the candy smoother and less grainy.
Baking soda
Reacts with the acid to release gas, making the candy lighter and more porous, and paler in color.
Butter
Adds fat that softens the texture and reduces stickiness.

The step that matters

Boiling until it hardens in cold water. Sugar concentration sets the final texture. Boiling too briefly leaves the candy soft and sticky, while boiling too long makes it brittle. The cold-water test shows when the syrup has reached the right concentration.
