I think it is an easy recipe. It needs 4 mackerel, clean and cut into 1 inch thick. Dry the fish with paper towel, mix some salt and let it set for couple hours. At meanwhile, prepare the sauce. The sauce needs soy sauce, sugar, garlic powder, 5 spice powder, rice wine. Cook all the ingredients with low heat and stir often (about 5-10 mins)d. After deep fry the fish, dip the fish with the sauce. enjoy. Thank you for liking my fish dish.
