At least in my house they are. 5 times I have tried to smoke these things and 5 times they end up rubbery (or too tough) and lacking of flavor. And no matter how much I think I have removed the membrane, there are still sections with a tough clearish thing on the bone side that is waiting to ruin my ribs. The last time I tried the 321 method. After an hour and a half in a 230 degree smoker, my ribs were already over 170 degrees. I wrapped them anyway and within 20 minutes the temp probe was beeping at me. I can't figure those things out. Besides, I really don't care much for ribs anyway. Not when there is the gift from God we call pulled pork. I suppose 6th time is a charm. Any advice for a guy who keeps getting whipped by ribs?
