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

What each ingredient does

Molasses: Provides the dark color and deep, slightly bitter sweetness that defines the caramel.
Sugar: Dissolves and cooks down to build sweetness and the chewy, set texture of the caramel.
Chocolate: Adds richness and flavor, and melts smoothly into the hot syrup.
Butter: Adds fat for a softer, smoother bite and rounder flavor.
