There are two kinds of "wet cake" shells. One is to knead flour with water into a round pancake blank with a diameter of about 15 to 20 cm and put it in the oven. The other is to repeatedly beat flour with water into tough and warm dough, grasp it in your hand, put it on a small flat pan and rotate it with slow fire, and wipe it into a paper-thin cake crust, which is called "wiping the cake". The fillings are generally carrots, winter bamboo shoots, green beans, dried beans, Chinese cabbage, cabbage, pork, cuttlefish, shredded scrambled eggs, oysters or fried oysters, shrimps, etc. Put them in different plates or fry them into a hodgepodge. In terms of accessories, there are fried rice noodles, oil-baked laver, sugar-fried peanut powder, Polygonum hydropiper, onion, garlic, coriander and so on. When eating, wrap the stuffing and auxiliary materials in the pancake skin, roll them into a tube, and eat them with both hands.
