Cut the front leg portion off, use that meat in chili mix. Leave the bone in the shoulder as this will radiate heat, and make it cook more completely. I use a rub consisting of: Garlic powder, brown sugar, black pepper, seasoning salts and oregano. Mix all that up real good, and while your shoulder is on the heat, slather it with a mixture of 30% Italian salad dressing and 70% melted REAL COW BUTTER. Take the meat off the heat and apply the mix liberally. Sometimes I wrap it in foil after I put all the stuff on, before it goes on the fire, and it sure turns out good.
