While I was smoking my boneless pork butt (from Costco) yesterday I got to thinking - does a bone-in pork shoulder take less time to cook than a boneless one? Does the bone heat up and help cook it internally? Less fat, etc. to render because of the space the bone takes up? Just curious more than anything. They didn't have bone-in ones at Costco but one of our other local supermarkets did. I guess the ultimate test would be to get 2 of the same weight - one with bone and one without and try!!
