I smoke St. Louis style ribs in my Charbroil grill using the 3-2-1 method and the ribs come out great. However, it is not an offset smoker. I can only fit 2 St. Louis style ribs on the grate. I put the charcoal in one half of the grill and smoke the meat indirectly on the other half. My question is if I want to use a rib rack and smoke 4 or more, can I still use this method of smoking, particularly when it comes to the second step wrapping the ribs in the foil? With the ribs inside the foil sitting vertically in the rib rack come out the same as if they were flat on the grating?
