What each ingredient does
- Sugar
- Provides the sweetness and, once cooked down, the firm body of the toffee.
- Cream
- Adds fat for a rich, smooth texture and helps the mixture thicken as it cooks.
- Flavouring essence
- Adds the main aroma and flavour once the mixture is removed from the heat.
The step that matters
Cook gently in the bain-marie until the mixture thickens. Indirect, gentle heat lets water evaporate slowly and the sugar concentrate evenly, reducing the risk of scorching on the base. Stirring keeps the mixture from sticking and burning, and the toffee is ready when it pulls away from the pan sides.
