For direct grilling, arrange coals by using long-handled tongs to spread them evenly in a single layer. Extend them about 1 inch beyond area of the food.
For indirect grilling, you need a disposable drip pan large enough to cover the surface below the food. Use a purchased disposable foil pan or make your own from a double thickness of heavy foil. Place the drip pan in the center of the firebox. Use long-handled tongs to arrange the coals around the pan.
