Curious on how you cooked it and how you served it? We really like sirloin, but never thought about cooking a whole butt. Always done just steaks or a sirloin roast (which end up being like a large steak IMO).
I was on a bit of a tight schedule this weekend,so I split it in two so it would cook quicker. I cooked it at 230 for till it hit 140 (about 6 hours) and then pulled and rested it for a couple of hours. Then I sliced it fairly thin with a knife. I always liked a good tri tip, but I thought this was better. I'll be picking up some good coleslaw on the way home to try it as a sandwich.
This whole thing was kind of an expensive experiment. I was curious what a really good cut of meat would be like on the smoker. I'm a fan. Definitely a bit pricey to do very often, but I will be doing it again.
