Prep: Apply a thin mustard slather and a generous coating of your dry rub to the ham before letting it sit at room temperature for 45 minutes to take the chill off.
BGE Setup: Light the lump charcoal with three chunks of hickory and stabilize the Big Green Egg at 275°F for indirect cooking with the convEGGerator legs up.
The Double Smoke: Place the seasoned ham in a V-rack over a drip pan with apple juice and onions and smoke uncovered for approximately 2 hours until the exterior is a deep mahogany.
Color & Temp Check: Verify the internal temperature is between 90°F and 105°F before moving to the next phase. This technique ensures the bark is set before you lock in the moisture.
The Steam Wrap: Wrap the ham tightly in heavy-duty aluminum foil to create a humid "microclimate" that relaxes the muscle fibers as the temperature continues to climb.
The Moisture Window: Maintain the wrap for approximately 45 to 75 minutes until the internal temperature reaches a steady 130°F. This process provides a way for the meat to stay juicy while preparing for the final lacquer.
The Glaze Prep: Combine the maple syrup, bourbon, and brown sugar in a saucepan and simmer over medium heat for 30 minutes until the liquid reduces into a thick, sticky syrup.
The Paint Job: Remove the foil once the ham hits 130°F and paint a thick layer of the Maple Bourbon Glaze over every square inch of the meat.
The Final Set: Close the dome and allow the glaze to caramelize for 15 to 30 minutes until the internal temperature hits the target of 140°F to 145°F.
The Rest: Pull the ham from the Egg and let it rest on a carving board for at least 10 minutes. This technique ensures the juices settle and the glaze firms up into a shimmering, "candy-like" crust.
The Slice: Identify the bone and make a vertical cut to release the large muscle sections before carving one-quarter inch slices against the grain for maximum tenderness.
