Combine all brine ingredients in a large container like a Briner Bucket. Whisk to dissolve. Add the ham to the solution, shank bone up. Lock the plate in place to keep it submerged. Place in a refrigerator for 8 days, or 1/2 day per pound.
Remove from brine. Rinse well under cold water. Place on a cooling rack, over a sheet plan. Place the ham in the refrigerator for 12-24 hours to form the pellicle (surface becomes tacky).
Remove the ham from the refrigerator. Preheat your Yoder Smokers YS640 pellet grill to 250°F. Season the ham with the R Butts R Smokin’ Ozark Heat. Smoke for four hours. Increase the smoker’s temperature to 350°F. Cook until an instant read thermometer inserted into the deepest part of the meat reads 140°F, about two more hours.
Mix together the glaze ingredients in a bowl. Place the ham in a large pan and place the pan in the smoker. Brush the glaze on the ham. Continue cooking until the internal temperature reaches 150°F. Glaze again. Continue cooking until the internal temperature reaches 155°F. Remove from the grill and let rest 30 minutes before slicing.
