What each ingredient does
- Grapes
- Provide the fruit pulp, flavour, and natural pectin and acid that help the jam set.
- Sugar
- Adds sweetness, helps the jam set, and helps preserve it.
The step that matters
Boil hard until it sets. Sugar and pectin form a gel only when the mixture reaches a high enough concentration. Boiling too briefly leaves the jam runny, and the saucer test shows whether it has reached the set point.
