What each ingredient does
- Plums or damsons
- Supply the fruit flavour, natural pectin and acid that help the jam set.
- Sugar
- Sweetens the jam, helps it set and preserves it by binding water.
The step that matters
Boil quickly until the setting point is reached. Setting depends on the mixture reaching the right concentration of sugar and pectin. Boiling too little leaves the jam runny, while boiling too long can make it stiff and dull in flavour.
