Method

  1. 1. Place all the berries and the lemon juice into a large stainless steel pan and warm through over a low heat, stirring now and then, until soft and juicy. Push gently with the back of a wooden spoon to release as much juice as you can, without reducing it to a pulp.
  2. 2. Pour in the sugar and stir often for a good 7 minutes, until the sugar dissolves (if it doesn’t dissolve completely before you boil the jam, it will have an overly sweet taste). Then increase the heat until the mixture reaches 105°C on a sugar thermometer, 10-15 minutes.
  3. 3. Remove the pan from the heat, skim any impurities off the surface and leave for 5 minutes to cool slightly before stirring. Soft berries have a tendency to float to the top during the setting process, so try to mix it all up before pouring into sterilised jars.
  4. 4. Cover the surface of the jam with waxed paper discs and secure the lids tightly on top. When the jars have completely cooled, label and store in a cool cupboard.

Chilli Jam

November 13

The original quantities are doubled here, as I prefer to make a larger batch. This makes 1 litre of chilli jam. In this case you really need to sterilise the jars you use in order for the jam to last longer. To sterilise the jars and lids really the simplest way is to put them through a dishwasher cycle and make sure not to touch the inside of the jar and lid. This recipe makes approximately 1 litre of jam; I distributed this amongst a variety of jars. You can check what fits by filling them before hand with 1 litre of water from a measuring jug.
