  • 1.7 kg / 3 lb 12 oz seedless grapes I used equal quantities or red, black & green grapes
  • 1 kg / 2 lb 3 oz granulated sugar
  • 3 tbsp lemon juice


  • Place grapes, sugar and lemon juice into a preserving pan or similar.
  • Using a gentle heat dissolve the sugar slowly, stirring frequently.
  • As the mixture heats up break up some of the grapes with your wooden spoon or use a potato masher in order the release the grapes’ juices.
  • Once all the sugar has dissolved fully (around 20 minutes) take the mixture off the heat and use a stick blender to blend the grapes to a juice like consistency.
  • Put pan back on the heat, bring to a rolling boil and then time for 25 minutes, stirring continuously. (You could start with 23 minutes as depending on freshness and variety of grapes the setting time can vary a little).
  • Take the pan off the heat and test for set by placing a few drops of the jam on a chilled saucer and place in fridge for a minute.
  • The jam should form a crinkle when you push your finger through it.
  • If not then boil for another 2 minutes and re-test until set is achieved.
  • Pot up in hot jars and place lids on immediately.
  • Store in a cool dry place and once opened keep in fridge.


Before you start:
Put 2 - 3 saucers in the freezer.
Sterilise 3 x 0.5 ltr jars by washing in hot soapy water (or take straight from dishwasher), fill with boiling water, empty and then place in oven for 20 minutes at 140°C where you leave them until the jam is ready. Washed lids should be sterilised with boiling water and then left to drain.
