I think that cut is called a Boston Butt. I'm not making this up. LOL. I put on a coating of rub and I put kikkoman teryaki (the runny stuff) in a spray bottle and give the P.I.G. pork a spritz every so often to keep the thing moist. Keep the heat low and cook it slow, and you'll have moist and tender.
Well, I've shoved my Boston Butt into the fridge with the dry rub rub a dubbed into it to sit overnight per the recipe...
It's already looking good!
