There are two kinds of potato balls. One is to choose smaller potatoes (3cm round) and wash them without peeling. Add pork belly into the pot and stir-fry them to get oil. Add potatoes until the water content of the potatoes decreases and the skin shrinks. Add soy sauce, soy sauce and other seasonings to stew until the juice is collected, and then take them out of the pot for eating. Another method is to peel the potatoes, steam them or cook them to make them into mud, add seasonings and mix them evenly. After cooling, they are manually made into small balls. Add oil to the pot to 6.
