My method may be a little longer and a little more time consuming, but I can say that after three years of using the SmokinTex I've hit the championship ribs.
I first pull the membrane off each slab. I then rub my special dry rub on both sides. I place them on the racks and and turn the temp to 220 and use apple wood for the smoke. I fully load the smoker box. I smoke them for 3 hours. I then take each slab and individually wrap them in foil and place them back on the racks for another 5 hours. (Yes, for 8 hrs total) You only need 3 hours of smoke for a great taste. Usually the box is all ashes. The foils helps tenderize them during the rest of the cook. I then take them out and let them set for an hour. At this point I have a non flare-up stainless steel grill heating up and I then take my sauce/glaze with my rub mixed in it and sear the the ribs to perfection. The rub and sauce is half the perfection, but the long smoke really makes them tender. I have people all of the time tell me I should open a restaurant or enter competitions. I have to say, they are awesome. Enjoy! Happy Smokin! :-)
