Davidson’s Plum Jam Recipe
See my post on Davidson’s Plums
500 gm fresh Davidson’s Plums (**see below for frozen)
500 gm sugar
juice of half a lemon
½ a vanilla pod – split open
Packet of pectin (eg: Jamsetta) just in case
(Makes 2 x 250gm pots – I usually double this recipe)
- Wash the plums to remove any dust or dirt. Cut the plums in half and make sure that you remove the two small seeds. Wear gloves if you don’t want to end up with nasty purple fingernails.
- Put the plums, lemon juice and sugar into a saucepan and add just enough water to stop the bottom layer from burning (approximately 20mls) – no more or it will take too long to reduce.
- Bring the fruit to a simmer very slowly, stirring all the time to ensure that the sugar is dissolved before the liquid starts boiling.
- Add the vanilla pod.
- Put a small saucer in the freezer to chill
- Leave on a gentle simmer for 1-2 hours until the mixture has thickened and reduced. Test the jam by dropping a teaspoonful on the frozen saucer – it should almost immediately thicken.
- Sometimes (often), if the plums are not very ripe or particularly watery, the jam will not set, and rather than use more sugar I will add the pectin. Follow the instructions on the packet, and don’t add too much until you have tested again on a saucer.
- When you are happy with the set, remove the vanilla pods.
- Allow to cool slightly. If you want a smooth jam, you can blitz with a stick blender. Then spoon into sterilized jars. ** Frozen plums – I often freeze my plums in 1Kg containers. If you do this, the seeds can easily be squeezed out of the half defrosted plums. Also, I only recently learnt that if you freeze fruit, it reduces the gelling effect of the natural pectin. So you will definitely need Jamsetta or similar.
Occasionally my jam just refuses to set, or I run out of pectin.
Don’t worry, it makes a great sauce on chocolate ice-cream!
