What each ingredient does
- Lump sugar
- Caramelises to a brown liquid that gives the colouring its colour.
- Butter
- Adds fat that softens the caramel and gives a smoother, rounder finish.
The step that matters
Heating the sugar until bright brown. Sugar caramelises quickly once it darkens, so heating it gently and stirring constantly prevents scorching, which would leave a bitter, burnt taste rather than a clean brown colour.
