Smoked two racks of baby backs yesterday. They were 2 identical racks for the most part and did everything the same. The problem one rack was absolutly great, tender and juicy but the other rack was really tough. The only thing that was done different, was on one of the racks for the life of me i couldn't get the membrane off. The problem i don't remember which rack, the good or the bad. Would not taking the membrane off make the one rack tough and not as juicy?
