I have seen this a few times on BBQ pitmasters and was looking for some tips for anyone that has done this. What IT are you looking to hit? Do you keep the skin on or remove before smoking?
I watched the video and The meat looked very slimy with fat and stringy you was correct
Throw a bit of brown sugar and rub on it, smoke for flavor, cube and then tighten up a bit on a hot grill. Serve as an appetizer. Pork Candy! A little goes a long way.
Like Dutch said, seems like bellies would be mostly fat if pulled and the idea just doesn't appeal to me. I know belly can be "stringy" if not handled properly.
