Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and, as it concentrates, the firm set and deep color.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter flavor.
- Flour
- Thickens the mixture so it holds together as it cooks.
- Butter
- Adds fat for richness and a smoother, softer texture.
- Grated chocolate
- Adds chocolate flavor, richness, and dark color to the mixture.
The step that matters
Boil until the mixture hardens on the spoon. As water evaporates, sugar concentration rises and determines the set. Stopping too early leaves the mixture soft and sticky, while boiling too long can make it brittle or scorch. Stir frequently so it does not burn on the bottom of the pot.
