Just picked up one of these at the supermarket-mainly for the fact it was on sale and was small, only about 3lbs. Then I got thinking about what it really is? Is it just part of the shoulder? Or has the whole putt been cut up into smaller chunks? Not really concerned as I plan on cooking it the usual pork butt method, although only for 5-6hrs. Was just curious as to what this piece of meat really is though.
