The cooking method I am using for these baby back ribs is a 3-1-1 method. This means three hours smoking, one hour cooking wrapped in foil, and then another hour unwrapped to finish off. You do not need to use this method and can simply grill the ribs unwrapped through the whole process. However, wrapping will steam the ribs and make them more tender.
Because the heat is to one side of our cooking area, it will be important to rotate the ribs as they cook to keep the heat even. I will be flipping and switching the two racks I am cooking after 1 1/2 hours. If you do not wrap the ribs, continue flipping and switching them every 1 1/2 hours.
