What each ingredient does
- Grape pulp or juice
- Supplies the fruit flavour and the natural pectin that lets the jelly set.
- Sugar
- Sweetens the jelly and helps it set as the mixture thickens when boiled.
The step that matters
Boiling the sugar mixture. The jelly sets only when enough water has evaporated and the sugar and pectin reach a gelling concentration. Boiling too briefly leaves it runny, while boiling too long can make it stiff, dark, or prone to crystallising.
