Cats, Through a lot of trial and error my husband has finally gotten BBQing ribs down to perfection. He marinates them with mesquite, garlic salt and onion powder. The next day he turns both burners on the grill to high, then shuts off the front one and lets the back heat up for about 5 to 10 minutes. Then puts the ribs to the front and shuts the lid and lets them go for about an hour and a half for a small rack to two and a half for a large one. Just before they are ready he slathers on the Sweet Baby Ray's BBQ sauce and lets them glaze up nicely. Sweet, spicy and hot. Ummm. Hugs, Marle P.S. We have a Weber 200 series grill.
