Growing up in Chicago, I always liked Carson's Ribs. They do not use a rub. After a got my smoker a few years ago I ran across their recipe and have enjoyed it ever since. Altho the recipe shows a kettle grill, it works fantastic in my GOSM. This isn't for everybody of course, but it is what I grew up with. Here is a link to the recipe.http://www.ribs.com/foodnetwork
My wife usually makes the sauce and I have also used Dave's BBQ sauce with success. I know some of you say the sauce will burn as you dip the whole slab in before even starting. It doesn't. The tips of the bones get a lttle dark, but the rest just a nice even reddish bark.
Now having said that, this weekend I plan on doing a dry rub just to see what everyone talks about. I was just getting tips when I ran across this thread. But for a no dry rub rib recipe, you can't beat this method. 3 racks of baby backs usually are done in 3 to 4 hours. We are not fond of the fall off the bone ribs and this does it just right.
