What each ingredient does
- Plums
- Provide the fruit itself, supplying the main flavor and the texture that the preserve keeps.
- Sugar
- Adds sweetness, which is added to taste when the preserved plums are used.
The step that matters
Heating the jars in the oven until the top plums begin to crack. Heat softens the fruit and drives out some air, so the jar can be filled and sealed well. Heating too long makes the plums soft and collapsing, while stopping too early leaves the fruit unevenly warmed. Watching for the first cracks helps keep the fruit firm.
