Can You Grill Pork Shoulder?

Grilling is suitable for any meats as long as the heat can penetrate through the thickness of it. So the thinner the meat the easy it will cook by grilling. A pork shoulder is a large lump so the outside would cook leaving the inside raw. It could be grilled on a low heat for a long time whilst turning on a spit[like hog roast or kebab meat]

Yes, but it will take a long time & should be cooked over low heat with wood chips
