Equipment

  • 2 Tea plates or saucers - placed in the fridge before you start making the jam.
  • Preserving pan - I use an 8.5 litre Penguin Home Professional pan.
  • jam funnel – definitely something I wouldn’t be without as it saves a lot of mess and waste.
  • 4 x 350 g Sterilised jam jars and lids
  • jam thermometer

Ingredients

  • 1.5 kg fresh ripe plums about 1350g after stoning
  • 1.25 kg granulated sugar

Instructions

  • Stone and cut the majority your plums in half. Chop the rest into smaller pieces.
  • Put the plums in a preserving pan and add 200ml water. Bring to a simmer and place on a lid.
  • Cook for about 10 - 15 mins until the plums are tender but not falling apart.
  • Add the sugar and, over a low heat, let the sugar dissolve slowly without boiling. This is likely to take about 5 mins.
  • Check the sugar has completely dissolved before increasing the heat to medium.
  • Bring to a gentle rolling boil and cook for around 15 minutes or until the jam thermometer reaches 104℃ / 220F.
  • Test for setting point using the wrinkle test. Remove your pan from the heat and drop a little jam onto an ice cold saucer. Then gently push the jam with your fingertip - if the jam crinkles, setting point has been reached. If not, boil the jam for a couple of minutes more and then check setting point again.
  • Once setting point is reached, ladle your jam into warm, sterilised jars before sealing with airtight lids.
  • Store in a cool, dry place out of the sunlight and use within 12 months.

Notes

  • The recipe makes enough (approximately) to fill 6 x 350g jars.
  • Serving size is based on one tablespoon (approximately 15 g)
  • Keep to 1.5 kilo of fruit or less for each batch of plum jam. I've used red plums,
  • Victoria plums or damsons make good plum jam too.
  • Your Homemade Plum Jam will keep for up to a year. Store in a cool, dry place away from direct sunlight.
  • Once opened, refrigerate and use within 4 weeks.
  • Nutrition information is approximate and meant as a guideline only.
