What each ingredient does
- Molasses
- Adds deep, dark flavour and moisture, and helps the candy turn chewy as it cooks.
- Sugar
- Provides sweetness and forms the crystalline body of the candy as it cooks.
- Butter
- Adds richness and fat, giving the candy a softer, smoother bite.
The step that matters
Boiling to the right consistency. Sugar syrups set according to how far their water has boiled off. Stopping too early leaves the candy soft and sticky, while cooking too long makes it hard and brittle. Checking the consistency carefully matters most.
