Eviscerate and De-Scale the fish if not already done, then rinse the inner cavity well.
Make three diagonal slashes into each flank of the fish.
Blend together the Soy Sauce, the Rice Wine, and the Sugar, stirring well.
Sprinkle the cavity with some of the Soy Sauce mix, then stuff it with the Garlic, Scallion and Ginger.
Rub the fins and Skin of the Fish liberally with the Salt, and work some into the into the slashes on the sides. Repeat using the Soy Sauce mixture as well.
Grill the fish over a moderately hot flame for about 15 to 20 minutes per side until the flesh is tender and a little charring has developed.
Remove from the grill and allow to rest for a few minutes before serving.
