Grilled Fish Here is a recipe for grilled fish. I have had it with Large & Smallmouth Bass,Walleye but it should work equally well for Salmon/Tuna/Trout/Perch and probably Cod/Halibut. Marinade 1/4 Cup Orange Juice 1/4 Cup Extra Virgin Olive Oil 1/6 to 1/4 Cup Prepared (plain or fancy ) Mustard 1/4 Cup Apricot Preserves or Orange Marmalade Blend together. Cover Thick Fish Fillets with Marinade for 2 hours. Make a fire on one side of a covered grill (or use a gas grill). Place fish in a wire basket and grill (covered) on the side WITHOUT the flames for about 7-10 minutes per side - baste with remaining marinade while grilling. Finish on the flame side but be careful that the Marinade does not blacken.
