In a bowl, mix together the brown sugar, honey, Dijon mustard, apple cider vinegar, and ground cloves to create the glaze.

Place the ham in the slow cooker and pour the glaze over the top, ensuring it is well coated.

Cover the slow cooker and cook on low for 4-6 hours, or until the ham is heated through and tender.

Baste the ham with the glaze every hour for maximum flavor.

Once cooked, remove the ham from the slow cooker and let it rest for 15 minutes before slicing.

Serve warm with your choice of sides.
