So I deboned the fish steak and slice it into smaller pieces, marinate it with some pepper, salt and cooking wine, set aside for about 30min. Then coat each slice with some cornstarch, place the fish slice in hot oil and fry it till golden color. Dish and set aside.
Pour the teriyaki sauce into the wok, let it simmer till thicken, pour the fish slice back into the wok and coat the fish with the sauce. Dish and serve.
