In a medium saucepan, combine the brown sugar, orange juice, Dijon mustard, apple cider vinegar, cinnamon, cloves, and ginger.
Place the saucepan over medium heat and bring the mixture to a simmer. Stir occasionally to help dissolve the brown sugar.
Let the mixture simmer for about 10-12 minutes, or until it thickens slightly and becomes syrupy. If you prefer a thicker glaze, continue to simmer for an additional few minutes.
Once the glaze reaches your desired thickness, remove the saucepan from the heat. Season with salt to enhance the flavor.
Brush the glaze generously over your ham during the last 20-30 minutes of roasting, applying a layer every 10 minutes to build up a beautiful, caramelized crust.
Once your ham is fully cooked and the glaze is bubbly and golden, remove from the oven and allow the ham to rest before serving.
