Damson Jelly
Ingredients
Directions
Extract the juice
Bake the damsons and bullaces in a slow oven or boil them in a water bath until soft.
Pour off the juice from the fruit, strain it, and weigh it.
Make the jelly
Boil the juice quickly without sugar for 25 minutes.
Remove from heat, stir in 10 ounces of sugar for each pound of juice, and boil for an additional 6 to 10 minutes, skimming off any scum.
Stir the mixture often before and after adding the sugar.

What each ingredient does
- Damsons
- Provide the fruit flavour and natural pectin that lets the juice set into jelly.
- Bullaces or pale plums
- Add more pectin and body to help the jelly set.
- Sugar
- Sweetens the jelly and helps it set firm and keep well.
The step that matters
Boiling the juice with sugar. Sugar must be added after the juice has boiled down, and the mixture needs a full rolling boil for the set to form. Stirring often keeps the sugar dissolved and prevents scorching on the bottom of the pan, which would spoil the flavour and colour.
