Ingredients
- 1500 g green plums
- 1250 g granulated sugar
Instructions
- Place the plums in a large preserving pan with 100ml water. Turn onto a gentle heat and cook the plums until they have broken down into a thick pulp.
- Remove the plum stones manually which should be floating within the pulp.
- Pour the granulated sugar into the pan with the pulp.
- Heat the pan and bring to a rolling boil, making sure to stir the bottom of the pan frequently so the fruit doesn’t stick.
- Boil the jam hard for 5 minutes, whereupon it should have reached setting point.
- Turn the heat off the jam and check for setting point with the wrinkle test.* If it doesn’t wrinkle then turn the heat back on and boil again for 2 more minutes before testing again.
- Once the jam has reached setting point then decant into sterilised jars*.
Notes
*The wrinkle test requires you to put several small saucers in your freezer when you begin making your jam. Once you think the jam might be ready then you can test it by removing a saucer from the freezer. Drop a teaspoon of jam on the saucer and then place it in the fridge. After about 30 seconds remove the saucer and push the jam with your finger. If the jam wrinkles up it’s ready, if it just pools back into the space your finger has left then it needs more bubbling time. Boil it 2 minutes more before testing again with another saucer.
*To sterilise the jars place the very clean jars you would like to use in an oven pre-heated to 140°C for 20 minutes. Sterilise the lids by dropping them into a saucepan of boiling water for 10 minutes with a splash of vinegar. I don’t sterilise my lids in the oven as they tend to ruin.
Storage - Unopened the jam will last for up to a year if stored in a cool dark place. Once opened keep in the fridge and the jam should last a month.
