What each ingredient does
- Barberry juice
- Provides the main flavour and liquid base of the jelly.
- Apple juice
- Adds natural pectin and liquid to help the jelly set.
- Sugar
- Sweetens the jelly and helps it set into a firm gel.
The step that matters
Boiling briskly after adding sugar. Sugar must be dissolved and the mixture brought to a hard, rapid boil so pectin and acid can form a gel. Too little boiling leaves the jelly runny, while overcooking can make it stiff or cause sugar to crystallise. Testing on a cold spoon shows when it has reached the setting point.
