What each ingredient does
- Plums
- Provide the fruit flesh, which gives the preserve its body, texture and tart-sweet flavour.
- Sugar
- Adds sweetness and, at high concentration in the syrup, helps preserve the fruit by drawing out water and slowing spoilage.
The step that matters
Bringing the plums and syrup to a full boil before canning. Boiling heats the fruit and syrup through, which helps destroy spoilage microbes and lets the jars seal. The sugar built up through the repeated syrup treatments is what keeps the fruit preserved afterward.
