Going to smoke some pork ribs on the grill, with a smoker box, planned temp with closed cover is about 90C (194F), but for sure less then the boiling point. This will probably take about 2:30 - 3 hours. Is there anything I can do to use the space on the grill for roasting some garlic while ribs getting done? I am used to add some oil and cover them in foil, then roast on high temp for about half an hour. But now it is going to be relatively low temps.
