Preparation

  • Place the cranberries, blueberries, strawberries, currants and lemon zest in your Tower pressure cooker crock pot.
  • Stir in the sugar and leave for around 1 hour until the fruit has fermented a little.
  • Add the water and salt. Place the uncovered cooker on medium-high heat and bring to the boil, stirring frequently.
  • Lock the pressure cooker lid into place and gradually increase the heat to bring to pressure.
  • When pressure has been reached, lower the heat to medium-low and maintain pressure for 10 minutes.
  • Remove the pressure cooker from the heat and use the natural release method to safely open (this should take around 18-10 minutes).
  • Remove the lid. Put the cooker back on medium-high heat and bring to the boil.
  • Boil for around 5 minutes, stirring frequently until the ‘gelling point’ has been reached. This can be tested by dipping a cold, stainless steel spoon into the boiling mix, removing and raising around 12 inches above the pan, and then turning the spoon. If the mixture forms two droplets that form a sheet that hangs from the edge of the spoon, the jam is ready.
  • Remove the pressure cooker from the heat, skim off any foam and then ladle the jam into hot, sterilised jars or containers. You should aim to leave around a half-inch space at the top of the jars.
  • After ensuring that the containers are securely sealed, cool and refrigerate or freeze.
