What is the Indirect Method of Cooking?

The Indirect Method is similar to roasting, but with the added benefits of that grilled texture, flavor, and appearance you can't get from an oven. Heat rises, reflects off the lid and inside surfaces of the grill, and slowly cooks the food evenly on all sides. The circulating heat works much like a convection oven, so there's no need to turn the food.

Use the Indirect Method for foods that require 25 minutes or more of grilling time or for foods that are so delicate that direct exposure to the heat source would dry them out or scorch them. Examples include roasts, ribs, whole chickens, turkeys, and other large cuts of meat, as well as delicate fish fillets.
