What each ingredient does
- Damson plums
- Supply the fruit flavour and natural pectin that helps the jam thicken as it cooks.
- Loaf sugar
- Adds sweetness, draws water out of the fruit, and helps the syrup set and keep well.
The step that matters
Cooking the plums until tender and clear. The plums must cook long enough to soften fully and release pectin, and the syrup must thicken as water evaporates. Stopping too early leaves the jam runny, while cooking too long makes it stiff and dull.
