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 forms the crystalline body of the taffy as it cooks.
Butter
Adds fat for a tender, soft texture and a rich flavor.
Cream of tartar
Acid that helps prevent sugar from crystallizing unevenly, keeping the candy smooth.
Water
Dissolves the sugar so it can be heated evenly into syrup.

The step that matters

Boil until it reaches the hard crack stage. Sugar syrup must reach the correct temperature to set firm but chewable. Stopping early leaves taffy sticky and soft, while overcooking makes it brittle and hard.
