Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Gives the candy its dark color, deep flavor, and chewy body.
- Sugar
- Provides sweetness and forms the crystalline structure that sets the candy.
- Vinegar
- Adds acidity that helps prevent the sugar from crystallizing into grains.
- Butter
- Adds fat for a softer bite and helps keep the candy from sticking to the pan.
- Baking soda
- Reacts with the acid to foam and lighten the candy's color and texture.
The step that matters
Boil without stirring. Stirring while the sugar boils can trigger crystals that make the candy grainy. Cooking must reach the hard firm stage: undercooked candy stays sticky, while overcooked candy becomes brittle and may scorch.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
