In the process of dough fermentation, meat sauce can be made. Wash pork belly, cut into fine powder and cook with skin. Take out the skin, stir-fry the minced meat until fragrant, gradually add seasonings such as soy sauce, vinegar, pepper noodles, salt, ginger and garlic, stir-fry evenly, and finally add the cut bean skin and dried bean curd and cook until it tastes delicious.
Knead the fermented dough into long strips, tear it into small pieces, flatten it with the palm of your hand, roll it into a cake, and add a proper amount of meat sauce in the middle. Then fold the cake in half, compact it, and bake it slowly in a pan with low fire. When the cake embryo gradually hardens and the surface becomes Huang Shi, it can be taken out and enjoyed. This kind of Chinese hamburger cake embryo is not only fragrant, unique in taste, but also convenient to carry, which is very suitable for fast-paced modern life.
