How to Make It
Combine all the ingredients except the plums in a 6-quart slow cooker. Fold in ¾ of the plums. Cover and cook on high 2 hours. Uncover, fold in remaining plums and cook uncovered, 1 hour on high, or until the juices have thickened. Let cool and serve at room temperature or transfer to a container, cover, and refrigerate for up to one week.
