Instructions

• In a large mixing bowl, combine the sugar, raspberries, blackberries and strawberries. Leave for 15 minutes or until the sugar dissolves.

• Tip the mixture in to a large pan and place over a medium heat. Bring the berries to a boil, add the salt, lemon juice and lemon zest while reducing the heat.

• Simmer for 20 minutes, allowing the berries to break down and the mixture becomes thicker. Use the back of the spoon to mash the fruit if needed.

• Remove from the heat and carefully pour in to a glass jar and leave to cool completely with the lid on.

• The jam will store in the fridge for up to three weeks.
