Got ahold of some Bison racks and decided to do a 3-1-1. Memphis rub, removed silver skin. They looked and smelled great. The problem is that since they are so lean there wasn’t a lot of meat on the ribs. There was pretty much no fat so the ribs were really tough and hard to pull off the bone. The meat tasted good but just too tough to pull, almost annoying. I have one more rack. I think I’ll do 2hrs of smoke and then 2hrs wrapped and call it. All help is appreciated!
