What each ingredient does
- Grape juice
- Provides the liquid base and the grape flavor the jelly is built on.
- Granulated sugar
- Sweetens the jelly and, when boiled with the juice, helps it set into a firm gel.
The step that matters
Boil the juice and sugar for 20 minutes. Boiling drives off water and concentrates the sugar and the fruit's natural pectin, which is what lets the mixture gel as it cools. Boiling too briefly leaves the jelly runny, while boiling too long can make it stiff or dull in color.
