What each ingredient does
- Red plums
- Provide the fruit flavour, acidity and natural pectin that help the jelly set.
- Sugar
- Sweetens the jelly and binds water so the pectin network can form a firm gel.
The step that matters
Boil again until it jellies. Boiling concentrates the juice and sugar so the pectin can form a gel. Stopping too early leaves a runny jelly, while boiling too long can make it stiff and sticky.
