Step1:First, cut the pork liver into 5mm thick and even slices. Put water into the slices and soak in white vinegar for 30 minutes, then clean them.
Step2:Put garlic, ginger, 1 teaspoon old soy sauce, 2 teaspoons raw soy sauce, white wine, pepper, 1 / 2 teaspoon sugar, 5-spice powder in the pork liver. Marinate for a quarter of an hour.
Step3:Pour in two spoonfuls of sweet potato powder. Stir well with chopsticks. Each piece of pork liver should be stained with sweet potato powder paste.
Step4:Put the oil in the pot. When it's 70% hot, put the pork liver in one piece. Fry for about two minutes on a low heat, then turn the pork liver upside down. Continue to fry until both sides are scorched yellow. (the time depends on the thickness of the pork liver. Sprinkle with shallot to serve.)
Step5:The remaining oil in the pot will stir fry the shredded onion and red pepper. It can be used as a side dish and add more flavor.
