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

What each ingredient does

White sugar
Provides the sweetness and, as it cooks, the firm structure of the candy.
Molasses
Adds deep flavor, dark color and a chewy, moist texture.
Cream of tartar
Its acidity helps prevent the sugar from crystallizing into grainy candy.
Butter
Adds fat that softens the texture and gives a smoother bite.

The step that matters

Boiling until the mixture cracks in cold water. The sugar concentration rises as water boils off. Stopping too early leaves the candy soft and sticky, while cooking too long makes it brittle or scorched.
