What each ingredient does
- Grapes
- Provide the juice and natural pectin that help the jelly set.
- Sugar
- Sweetens the jelly and, with boiling, helps it thicken and set.
The step that matters
Boiling the juice with sugar. Sugar must be added to juice that has already been reduced by boiling, since sugar and heat together concentrate the mixture and help it gel. Boiling too briefly can leave the jelly runny, while boiling too long can make it stiff or cause the sugar to crystallize.
