Ingredients
Directions
Make the caramel
Combine grated chocolate, yellow sugar, molasses, milk, butter, and vanilla in a pot.
Boil the mixture for about 25 minutes, ensuring it is not too brittle.
Set and mark

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated chocolate
- Adds deep color, bitter flavor, and richness to the caramel.
- Yellow sugar
- Provides sweetness and, as it cooks, helps the candy set firm.
- New orleans molasses
- Adds moisture, a dark color, and a rich, slightly bitter flavor.
- Milk
- Adds fat and milk solids that soften the texture and mellow the sweetness.
- Butter
- Adds fat for a smoother, less brittle texture and a richer flavor.
The step that matters
Boiling the mixture. Sugar candy sets according to how far its water has cooked off and how hot it gets. Boiling too long makes the caramel hard and brittle, while stopping too early leaves it soft and sticky. Watching the texture during the boil keeps the set right.
