  • 900 g dessert plums (weight without stones)
  • 4 tbsp water
  • 900 g sugar
  • 2 tbsp lemon juice
  • 1 knob butter approx 1 tsp


  • Halve the fruit and remove the stones.
  • Wash your jars and place in a low oven (see notes).
  • Put into a large pan with the water and cook gently until the plums are soft but not disintegrated.
  • Add the sugar and lemon juice and stir until the sugar has dissolved.
  • Bring to the boil, and boil rapidly, (rolling boil) then remove from the heat after 5 minutes and test for set (see notes).
  • When setting point has been reached, skim off the most of the froth (scum) into a bowl (you can still eat this, it's not dirty just frothy) then add the knob of butter which will disperse the remaining scum.
  • Let it cool for about 15 minutes so the fruit settles and doesn't sink to the bottom of the jars.
  • Ladle into sterilised jars and leave to cool before sealing.



To Sterilise jars: thoroughly wash the jars, rinse in cold water, then turn upside down on a baking tray. Place in the oven and turn the heat on very low leave for about 15 minutes, remove just before filling.
To Test for Set: After about 5 mins, spoon a little jam onto a cold saucer. Place it back in the fridge for 2 minutes then push the jam with your fingertip. If it wrinkles, the jam is ready. If not, cook for a few mins more and test again, with another cold saucer. If you have a sugar thermometer, it will read 105C when ready.
