Turn these plump, juicy blackberries into a jar of gorgeous home-made Easy Blackberry Jam. It’s quick and easy and you only need a small amount to produce a couple of jars of sweet deliciousness!



400g (2 1/2 cups) blackberries

300g (1 1/4 cups) sugar

1 lemon, juiced

1 teaspoon cornflour


  1. In a medium saucepan add all your ingredients and over medium heat bring the fruit to a boil.
  2. Stirring frequently, allow the fruit to boil for 20 minutes until the fruit starts to thicken. Remove from the heat and place a small dollop on a cold saucer. Push your finger through the dollop and if it feels gel-like and wrinkles then the jam has reached setting point. If it isn’t ready then return the pan to the heat and boil for another five minutes before testing again.
  3. Ladle immediately into sterilised jars leaving 2 cm from the top and seal immediately with a screw top lid


How long does home-made jam last without using pectin?

Your jam will last a couple of months in a cool cupboard or for three months in the freezer. To thaw, place jar in the fridge until the jam has de-frosted. Once the seal has been broken then the jam has to be refrigerated.
