Course: Dessert , Breakfast , Snacks
Cuisine: American , British

Ingredients

  • 600 g firm blueberries stalks and mushy ones removed
  • 400 g granulated sugar
  • 1 tablespoon freshly squeezed lemon juice

Instructions

    Cup of Yum
  1. Wash the blueberries in a colander.
  2. Put the blueberries, sugar and lemon juice into a preserving pan.
  3. Place the pan over a gentle heat to slowly dissolve the sugar crystals, stirring with a wooden spoon from time to time.
  4. As the sugar starts to melt and the fruit warms up, take a potato masher to mash the blueberries, leaving some whole if desired.
  5. Once the sugar has completely dissolved turn up the heat and bring the pan to a rolling boil and time for 15 minutes, stirring all the while (to prevent the sugar burning on the base).
  6. Take the pan off the heat and test a few drops of the jam on a frozen saucer and place in the fridge for a minute. If when you push your finger through it the jam forms a crinkle and is gel like then it’s ready. Otherwise boil for another couple of minutes and repeat process until ready.
  7. Pot up the jam in a sterilised hot jar using a small ladle or jam funnel.
  8. Screw on lid immediately.
  9. See notes for storage instructions.

Notes

  • Put 2 saucers in the freezer before you start. Sterilise 1 x 450 ml jar by washing in hot soapy water or take straight from dishwasher, filling with boiling water, emptying and then placing in oven for 20 minutes at 140°C then leave in oven until jam is ready. Washed lids should be sterilised with boiling water and then left to drain.
  • Once cool in the jar this jam is ready to eat.
  • Store in a cool, dark, dry place and consume within 12 months for best colour and flavour although will be safe to eat for many years. Once open keep in fridge and use within a few months.
