Sweet, savory and smoky barbecue flavor doesnt have to come out of a bottle, as this recipe proves. Dig around among your spices and condiments, and its likely you can whip together this dry rub without running to the store. The method is equally easyjust dont skip the butter basting step halfway through. It adds lots of flavor, moisture and helps the roast to brown. Once your roast is cooked, youve got enough pork to feed a full house, whether you want to serve it on a bun, shred it for tacos or just serve it sliced with extra barbecue sauce on the side.
