Damson Jelly
Ingredients
Directions
Prepare the fruit
Select firm, dry, and ripe damsons. Remove the stalks.
Place the fruit in a large jar or stewpot and cover it tightly.
Extract the juice
Put the jar in a pot of cold water and cook slowly until the plums are tender.
Strain the juice through a jelly bag or fine cloth into a preserving pan.
Make and store the jelly
Add 1 cup (8 to 10 oz) of sugar for each pint of juice.
Boil until the jelly sets quickly when tested on a cold plate.
Pour the set jelly into jars and cover with paper brushed with egg white to seal.
Store in a cool, dry place.

What each ingredient does
- Damsons
- Supply the fruit flavour, acidity and natural pectin that help the jelly set.
- Sugar
- Sweetens the juice and helps the pectin form a firm gel as it boils.
The step that matters
Testing for the set on a cold plate. Pectin and sugar form a gel only at the right concentration. Stopping too early leaves a runny jelly, while boiling too long makes it stiff and dull, so test a spoonful on a cold plate before removing the pan from the heat.
