What each ingredient does
- Brown sugar
- Provides the main sweetness and body, and caramelizes as the mixture boils to form the toffee.
- Butter
- Adds richness and fat, giving the toffee a smooth texture and tender bite.
The step that matters
Boil without stirring until crisp in cold water. Sugar syrup boiled without stirring avoids forming large crystals that make it grainy. Testing a drop in cold water shows when it reaches hard-crack stage, so it sets crisp rather than chewy or sticky.
