Remove pork from refrigerator 1-2 hours prior to cooking. If the pork is still cold or partially frozen cooking time will be longer.
Preheat smoker to 250 Deg F.
Generously salt all sides of pork roast with the Hawaiian alaea sea salt just prior to cooking
Place pork in smoker and add wood chips according to smoker instructions. I use hickory wood chips but have also had good results with applewood
After 3 hours remove pork from the smoker and wrap in banana leaves and 2 layers of foil to seal in the moisture. Place the pork back into smoker. Check temperature after three hours, and every half hour after that until it reaches 190-200 degrees
Cooking times can vary anywhere from 6.5 to 9 hours depending on size of the pork shoulder
After pork has reached temperature remove it from smoker and let it rest for at least 10 minutes. Remove pork from foil and banana leaves and shred saving some of the juices
Meat should easily come apart but not disintegrate. If not using immediately place shredded pork in a container with reserved juices. Chill. To reheat the pork, spread over a large baking sheet and heat in a 350 Deg oven until hot. Keep warm before serving.
