I tried something a few cooks ago with my spare ribs. I was tired of struggling to pull the membrane off the ribs so I took a sharp knife and scored the ribs(not to deep) from top to bottom. The theory being that the membrane should shrink anyway and and the fat between them will render out. I was pleased with the results. Since one test doesn't really prove much I tried it again this weekend. The results were the same. The ribs passed the pull test for doneness and they were fall of the bone without foiling. I thought they might be a little on the dry side but that was more my fault than any scoring. Oh,by the way, LOVE THIS WSM. She kept temps rock steady for well over 8 hours and still had plenty of steam left
