My husband is scary when it comes to grilling anything. I fix our Boston Butts in the oven or slow cooker, depending on what I want to do with them. I've had several rub recipes, which I can't find now, of course, and I usually rub the whole Butt down with salt, pepper, garlic powder, curry posder, minced garlic, and some other stuff I don't recall like sage, thyme, rosemary. Then I pour a little orange juice over the butt, fat side up. Cover the whole thing and put it in a 325 oven and roast all day, or overnight, depending on size. When it's done, I slice it and we can have barbeque sauce with it (regular or Korean). I skim the fat off, then cook rice in the cooking juice. Mmmmm.
