Place any firm fish steak (sword, shark, tuna, halibut or salmon) directly on the grates over the hottest section. Sear steaks 1 to 2 minutes per side to seal in the juices. Finish cooking just slightly away from the hottest area, or finish cooking in a 450 degree oven if desired following the 10 minute rule.
Cover the grates with aluminum foil, oiled lightly. Season fish according to your tastes and cook on top of foil, skin side down, following the 10 minute rule.
Cook fillets in a foil “tent.” Place fillet on foil. Sprinkle with white wine and favorite herbs. If desired, lay sliced blanched vegetables on top of fillet. Seal foil making a “tent” which allows space for steam to collect. Cook according to 10 minute rule. Allow slightly more time if vegetables are on top of fish.
Stuff and/or season any whole fish to your tastes. Wrap in foil and place on the grill. Use the 10 minute rule per fish side, turning halfway through to cook evenly.
Pan frying and butter sautéing only require enough oil to cover the bottom of the pan, and a simple dusting with flour should suffice to coat the fish. Slices no more than 1/2 inch thick are ideal, and frozen fish should be at least partially thawed. Cook in oil heated to 375F until one side is golden brown, turn once and cook until the other side is done.
