Some fish are fragile and may break into pieces when you turn them on the grill. Sidestep the problem with a grill basket.
Inexpensive and invaluable, a grill basket can be adjusted to hold fish of varying thickness. When it's time to flip the fish on the grill, flip the basket instead. Greasing or oiling the basket before grilling helps prevent the fish from sticking. To keep from burning yourself as you turn the grill basket, use an oven mitt to hold the basket's metal handle.
