1. Place all the ingredients in a slow cooker, making sure the cabbage is slightly submerged. Cook on high for 20 mins, then reduce to low and cook for 1-1½ hours until the liquid becomes reduced and sticky. Leave to cool before transferring to food bags or containers and chilling or freezing.
2. On the day – pop back into the slow cooker to re-heat or simply warm in the microwave.
