Thank you. Makes total sense.
I'll weigh one tomorrow that I'm cooking but my gut feel is it's a fair bit worse than normal just simply because of the long process where so much fat renders. Plus the bone is removed. And in the way I do it, I remove a lot of the fat during the "pulling" stage that doesn't get used.
I've always heard it was closer to 50% for pork. And for sure, that's a "downside" of BBQ. A steak that's cooked for just a few minutes would have only a tiny bit of shrinkage obviously.
But it's why I was so interested in
@TheFanatic's insight that pork shoulder was so profitable.
