I wanted to do beef ribs this weekend, but the butcher and the supermarket were both out. So, I decided on a bottom round. I know it's not the best candidate for smoking, but I figured I would give it a try. I have a 5 and a half pounder. I'm going to do a dry rub and smoke it to 150. For maximum tenderness, should I foil and then put it back in the smoker, or should I just pull foil and let rest? Thanks.
