- Sugar
- Sweetens the juice and helps the jelly set and keep its texture.
The step that matters
Boiling the juice and sugar for twenty minutes. Boiling concentrates the juice and dissolves the sugar, so the mixture reaches the level needed to gel. Boiling too briefly can leave a runny jelly, while boiling too long can make it stiff or caramelised.
