I take the ribs and par boil them in water for 20-30 minutes until the meat is tender. I usually add a little (3/4 cup - 1 cup) of white vinegar, salt, black and red pepper, onion powder and garlic powder to he water as well.

In the last 10-15 minutes of boiling, I fire up all three burners on the grill. I put a smoker box with wood chips on one burner and wait till it starts to smoke. At that point, I turn off the center burner and turn the outer two down to medium (or if I have more meat to cook, I leave the center on and turn off the other two) - just make sure the smoker box is on a lit burner - put the meat on the unlit burner and let it cook for 10-15 minutes. Then add some bbq sauce, cook a little more, flip and baste the other side. If you like the meat crispy, you can turn one of the burners back to high and once at temp, sear it for flavor (not to hold in moisture as it will already be falling off the bone).

Give it a try. You will love them.
