I have tried hundreds of store bought marinades and home brews. One of the best I have every tried comes from a local place, (Virginia Beach) Ashman. It is available at all of the grocery stores in this area. It is in the seafood section. One of the great things about it is it does not over power the fish, even if left marinating overnight. Simple as can be, marinade fillets from 30 minutes to a day and grill or broil. Baste a little on while cooking works well too. Great on everything, tilefish, black sea bass, small blue fish, Spanish mackerel, flounder, trigger fish, spade fish, croaker, would make a cement block edible.
