Line a rimmed baking sheet with aluminum foil; set wire rack inside sheet. Place 12 inch foil square in center of rack (this will make clean up so much easier )😉 Set ham on foil, flat side down, and cover with oven bag, tucking bag under ham to secure it. Let ham sit at room temperature for 1 1/2 hours (don't skip) I know it is tempting.
Adjust oven rack to lowest position and heat oven to 325 degrees. Bake ham until it register 100 degrees, about 2 hours (don't puncture bag when checking temperature)
Meanwhile, combine sugar, brown mustard, vinegar, dry mustard, ginger, and cloves in medium saucepan and bring to boil over medium-high heat. Reduce heat to medium-low and simmer until reduced to 3/4 cup (15-20 minutes). Let cool while ham cooks
Combine panko, parsley, oil, salt, and pepper in bowl. Remove ham from oven, remove and discard oven bag, and let ham cool for 5 minutes. Increase oven temperature to 400 degrees
Brush ham all over with glaze. Press panko mixture against sides of ham to coat evenly. Bake until crumbs are deep golden brown, (20-30 minutes). Transfer ham, flat side down, to carving board and let rest for 30 minutes. (This is a great time to be finishing up your side dishes). Carve and Serve.
