What each ingredient does
- Barberries
- Provide the tart fruit pulp that forms the body and sharp flavour of the marmalade.
- Sugar
- Sweetens the pulp and, as it thickens on boiling, helps set the marmalade.
The step that matters
Reduce the pulp to half its volume. Evaporating water concentrates the pulp and its natural pectin, so the marmalade can thicken and set once the sugar is added. Too little reduction leaves it runny.
