What each ingredient does
- Elderberries
- Provide the main flavour and deep colour, along with natural pectin and acidity.
- Grapes
- Add extra pectin and acidity, helping the jelly set.
- Sugar
- Adds sweetness and, with the cooked fruit juice, helps the jelly set and keep.
The step that matters
Boiling the juice before adding sugar. Boiling the juice for 30 minutes concentrates it and activates the natural pectin, which is needed for the jelly to set. Adding sugar too early or skipping this boil can leave the jelly runny.
