How to Grill with Indirect Heat
When grilling over indirect heat, the food is not cooked directly over the heat source. The covered grill then acts like an oven, so there is no need to turn the food. The indirect grilling method is used for foods that require at least 25 min. of grilling time or foods that are so delicate that direct exposure to the heat source would dry them out, such as roasts, whole chickens, thick steaks, ribs or delicate fish fillets. To set up a gas grill for indirect grilling, light one side of grill leaving other side unlit. Close lid; heat grill to desired temperature. When ready to grill, place food on unlit side to cook as directed. If using a charcoal grill, preheat the grill by lighting the coals and heating them to desired temperature. Then, move the coals to outside edge of charcoal grate. Place the food in the center of the grill grate and grill as directed.
