hammersley... Spare ribs are what I do. I do them in a WSM (Weber Smokey Mountain) smoker. I don't remove the membrane, but I do trim all the meat flaps down considerable. I cover the meat side with rub and put them in the fridge while I get the charcoal fired up. I use 4 or 5 lumps of hickory and preheat to 225 to 230 degrees at the grate. Put the ribs on for 2 1/2 hours then put each rack in a plastic baking bag and do them until they have shrunk back from the bones a quarter to 1/2 inch. Usually 1 to 2 hours. Remove them from the bags, put them back on and slather them with Sauce (KC Masterpiece will work). Remove them with in 10 minutes and serve or slather them again then in another 10 minutes serve them.
I do them once every week.
