I did a 4lb rack of Beef Back ribs today. All I put on them was salt,pepper,and a little crushed Rosemary on them.Put them into the smoker at 225 degrees for 3 hours,pulled them out and wrapped them tight in foil with half a cup of beef broth,back in for another hour,then pulled the foil off and back in for 30 to 45 more minutes.Tender and really juicy, and they still had some "pull" to them,instead of falling off the bone. I believe you have to follow Okie's advice and wrap them so they can braise. I've done them before without the wrap and they were never this tender. No sauce either,I'm like Myron. I wanna taste the BEEF!
