Supergolden Bakes’ Easy Homemade Blackberry Jam

Supergolden Bakes’ Easy Homemade Blackberry Jam

Recipe developer and author behind Supergolden Bakes Lucy Parissi has loved blackberry picking ever since she was a child, and one of her favourite ways to make the most of the juicy wild berries is by making some delicious blackberry jam to spread on toast. This recipe is perfect for beginners and simply bursts with flavour.

Method for the Blackberry Jam
  • Put the blackberries in a pot and add the sugar. Stir gently, cover the pot and leave the berries to macerate overnight or for up to 12 hours. The sugar will draw out the juice and soften the berries and it will dissolve quicker when you make the jam.
  • Bring the fruit slowly to a rolling boil. Use a slotted spoon to skim the surface of any frothy scum.
  • Continue to cook until the rolling boil reduces down, the air bubbles subside and the surface of the jam looks glossy. Test your jam using the Thermapen – the setting point is 104.5°C-105°C.
  • Take the jam off the heat and allow it to sit for 10 minutes so that the fruit distributes evenly.
  • Fill warm sterilised jars to the top with the jam while it is still over 85°C. Seal and cool or simply pour the jam into an airtight container. Store the jam in the fridge and use within three weeks.
Notes
  • Use slightly under-ripe fruit which are naturally higher in pectin. Make sure you thoroughly rinse your blackberries to get rid of dirt.
  • To get rid of the frothy scum (trapped air) either skim the jam with a slotted spoon or stir in a little butter.
  • Fill warm jars to the top with jam while it is still over 85°C.
  • Shop-bought blackberries are larger and sweeter than the foraged ones. They are also lower in pectin so you will need to add some lemon juice to aid the setting.
  • Use a potato masher to break up the farmed berries slightly before cooking the jam otherwise the jam will be very chunky!
" My Thermapen is in constant use, whether I am making a roast dinner or baking bread! It's so versatile, easy to use and really takes the guesswork out of cooking! An absolutely essential tool that should be in everyone's kitchen."
