Lightly coat the inside of the slow cooker with cooking spray. Position the ham inside the cooker with the cut side facing downward. Place the lid on top to confirm that the ham fits snugly; if the lid doesn’t close properly, trim a small portion from the top of the ham and nestle it beside the main portion.

In a medium saucepan, blend together the brown sugar, honey, water, dijon mustard, cinnamon, and cloves. Warm over medium heat, stirring occasionally, until the sugar is fully dissolved, approximately 5 minutes. Evenly pour this glaze over the ham.

Secure the lid and set the cooker to LOW. Let the ham cook undisturbed for 4 to 6 hours, spooning the juices over the meat once every hour during the cooking process. Ensure the internal temperature reaches a minimum of 140°F (60°C) before serving.

For a thicker glaze, pour the cooking liquid into a saucepan and simmer over medium heat, stirring continuously until it reaches the desired consistency.
