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 cooks, helps set the mixture into a firm candy.
- Molasses
- Adds deep flavour and colour, and keeps the candy soft and chewy rather than brittle.
- Butter
- Adds richness and fat, giving the candy a smooth texture and a tender bite.
The step that matters
Cook over medium heat while stirring. Stirring keeps sugar from scorching on the bottom of the pan, and gentle medium heat lets the mixture reach an even, smooth consistency without burning.
