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

What each ingredient does

Grated chocolate
Adds deep flavor and a dark color to the caramel.
Brown sugar
Provides sweetness and moisture, and helps the caramel stay soft and chewy.
Molasses
Adds moisture, a rich toffee-like flavor, and a darker color.
Milk
Adds creaminess and moisture, softening the texture of the caramel.
Butter
Adds fat for a smooth, tender bite and a rich mouthfeel.

The step that matters

Boiling while stirring constantly. Sugar and milk solids can scorch on the base of the pot if not stirred constantly, giving a burnt flavor. The cooking time controls how firm the set caramel becomes, so a steady boil matters.
