Ingredients
Directions
Prepare the juice
Bake the damsons in a slow oven or boil them in a water bath until soft.
Pour off the clear juice from the fruit, strain, and weigh it.
Make the jelly
Boil the juice quickly without sugar for 25 minutes.
Remove from heat and stir in 10 ounces of sugar for each pound of juice.
Boil quickly for 6 to 10 minutes, stirring constantly and removing any scum.

What each ingredient does
- Fine ripe damsons
- Provide the fruit juice, rich in natural pectin and tartness that help the jelly set.
- Bullaces or pale plums
- Add extra pectin and body to the juice, supporting a firm set.
- Good sugar
- Sweetens the juice and, with boiling, helps the jelly set and keeps it preserved.
The step that matters
Boiling with sugar for 6 to 10 minutes. Sugar must be fully dissolved before a rapid boil, and the boil must be brief and vigorous. Overboiling can darken the jelly and reduce its fresh flavour, while underboiling may leave it too soft to set.
