Skewering the Pork and Grilling
Soak the bamboo skewers in water for 1-3 hours.
Skewer 5-6 pieces of pork onto the top half of the bamboo skewer.
Preheat the grill and oil the grill grates before grilling.
Place a double thick piece of aluminum foil toward the front of the grill to block the heat from the bamboo skewers so they don't burn.
Grill the skewers, turning every couple of minutes. Baste the glaze after each turn to allow the it to bake on.
Remove the pork from the grill when the internal temperature reaches 140°. While resting the pork, the temperature will rise about 5 additional degrees.
