I normally smoke baby backs that I only buy from BJ's, they come three racks to a cryopak and I have yet to get a bad pack. I decided to go to the local supermarket and bought two racks of St Louis since I didn't like the baby backs they had and if I had gone to BJ's I would have spent close to $200 extra buying extra meat and chicken to fill my freezer. Anyway, I didn't trim them before cooking and used the same rub I always use. I smoked them for 5 hours and they were tender but they seemed to be fattier then the baby backs and my wife and kids were not really crazy about them. I was just wondering, if this is the norm or did I just get a lousy pair of ribs. Thanks ~ Joe.
