Step #1 In a small saucepan mix the soy sauce, the sugar, the gingerroot, the vinegar, & pepper to taste & heat the mixture over low heat while preparing the fish.
Step #2 Pat the fish dry & Spice up it with salt & pepper.
Step #3 Have ready in separate shallow dishes the cornstarch, the eggs beaten with the salt, & the bread crumbs mixd with the sesame seeds.
Step #4 Dredge each fillet in the cornstarch, dip it in the egg mixture, & dredge it in the bread crumb mixture, letting the excess drip off, coating it thoroughly & shaking off the excess, pressing the mixture to help it adhere.
Step #5 In a skillet large enough to hold 2 of the fillets comfortably heat 1/4 inch of the oil over moderately high heat until it just begins to smoke, or until they are golden brown, in it fry the fillets, 2 at a time, for 45 seconds to 1 min on each side, reheating the oil between batches, & transfer them to paper towels to drain.
Step #6 Transfer the fillets to 4 heated plates, bring the soy sauce mixture to a boil, & spoon it over the fish.
