Pork belly is a deliciously flavorful barbecue delicacy that has received an explosion in popularity thanks to the enthusiasm for pellet grilling. Enjoyed as either an appetizer or meal, this smoked whole pork belly is cooked low and slow on the grill. Then after a bit of sauce is basted on top of the slab, the heat is turned up so the fat and skin can render a delicious crispy crunch to the taste buds.
