Mirabelle plum jam
St Matthew's Primary School let us gather some of the fallen plums under their formidable mirabelle plum tree. I've turned them into delicious jam, and wanted to share the recipe here.
What you'll need
Clean jam jars and lids - sterilised with hot water
1 KG stone fruit like plums, gages or cherries
1KG jam sugar
a pot with a lid
about an hour of your time
Step 1: wash
Wash the mirabelle plums with cold water.
Step 2: soften
Boil with very little water in a pot with the lid on, until the fruit turn soft.
Step 3: mash
I used a potato masher to separate the pulp from the stones.
Step 4: de-stone
Take off the heat and pass through a colander. I removed the last few stones by hand (once it's cool enough to touch).
Step 5: add jam sugar
Return the pulp to a pot, add jam sugar as per packet. Usually it's 1kg of sugar to 1kg fruit. Let sugar dissolve, boil for a few minutes. To test if it's ready to set, spread a spoonful of jam onto a cold plate and see if it thickens after a few moments.
Step 6: pot up
Fill the finished jam into re-used jam-jars.
