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

What each ingredient does

Sugar
Provides the sweetness and the bulk of the candy's structure as it cooks and hardens.
Karo syrup
Interferes with sugar crystallization, keeping the taffy smooth rather than grainy.
Cream of tartar
Acidifies the syrup, helping prevent sugar from crystallizing and keeping the texture smooth.
Butter
Adds fat for a softer, richer bite and smoother mouthfeel in the finished taffy.

The step that matters

Boiling to the brittle stage. Sugar syrup hardens as its temperature rises and water boils off. Stopping too early leaves taffy sticky, while going too far makes it hard and brittle. Testing in water shows when the syrup is at the right concentration.
