Ingredients
Method
Place berries, sugar and juice in a 4.5-litre (18-cup) slow cooker; stir to coat. Cook, covered, on high, for 4 hours.
Uncover, increase heat to reduce setting on high; boil, uncovered, stirring occasionally, for 30 minutes or until jam jells when tested.
Pour hot jam into hot sterilised jars, seal immediately. Label and date jars when cold.

How to sterilise jars
You will need to transfer the mixed berry jam into sterilised glass jars for storing. For our Test Kitchen advice on safely sterilising jars and storing jam, see this article.
