Shuangchengbao snacks are well known. At the end of the Qing dynasty, there was a saying that "there was Liaoyang mansion in the south and twin castles in the north". The first snack is "sweet and sour tea". In fact, "sweet and sour tea" is a kind of beverage made of millet and soybean after foaming, ground into juice with water mill, and then boiled and fermented. It can not only relieve summer heat and quench thirst, but also has the effect of invigorating spleen and appetizing, and its taste is similar to that of the current fruity yogurt. It is said that "sweet and sour tea" comes from jurchen era and has been popular in Manchu settlements such as Shuangcheng for hundreds of years. In the late Qing Dynasty, there were merchants making wine and selling in Shuangcheng market, and the most famous businessman was Liu. Liu Zu was born in Laoting, Hebei Province, and was engaged in the production of sour tea, nicknamed "Liu Sour Tea". In the 1930s and 1940s, in the summer, many families in Shuangcheng brewed "sweet and sour tea", and the street was full of hawking.

At that time, there was a "one-point profit" restaurant at the entrance of West Street, and its main business object was farmers who went into the city to handle affairs and do small business. Mainly engaged in shredded chicken tofu, Melaleuca straw hat cake and pork bone soup. After his family baked a thousand layers of straw hat cake on the table, he gently lifted it with his hand and it fell like noodles. Tofu brain is sold in large and small bowls. Bowls are very learned, and they are all the same size from the outside. The difference is that the bottom of the small bowl is thick, the bottom of the big bowl is thin, and there is no grade for eating at the same table. This is called humanized service. Pork bone soup is made in a large iron pot, and it costs nothing to drink. His family also sells a cheap "white flour" (noodles), which can be mixed with soy sauce and is very popular among farmers.

In the bustling "Miaotou" market, there is a "Xue Jia Pie Shop" that has not opened. This kind of pie is famous for its thin skin and big stuffing, tender outside and tender inside. Its stuffing is fixed with two kinds of vegetables, zucchini and winter cabbage. The difference is that it uses canned pork and stuffing. It is said that canned pork oil is delicious and better than pork stuffing. "Ximen Lianer" has a "Song Ji Mahua Shop". The twist fried with ancestral secret recipe is brown in color, crisp and delicious. "Jia Ning Cake Shop"' s chopped green onion oil cake has been sold by OEM, and the cooked elbow is rolled up while it is hot. It is oily but not greasy and full of fragrance.

In winter, the wonton stall in the "Temple Head" is very distinctive. There is a charcoal stove in front of each booth and a big iron bowl next to it. When diners patronize, the operator puts wonton in a big iron bowl and then heats it on a charcoal stove. People who eat keep warm while eating, and the more they eat, the hotter they get. In midsummer, there is a common snack called "hot and sour bowl tuo" on the street. Its main ingredient is buckwheat noodles, which are fermented, steamed in a steamer, cooled and sliced, and then mixed with soy sauce, vinegar, Chili oil and other seasonings. It's really hot and sour and delicious, and it can relieve summer heat and stimulate appetite. Operators or carts, or carrying loads, walk the streets and lanes, shouting melodiously.

Shuangbao is rich in rhubarb rice and kidney beans, and every woman is a good hand at making "sticky dry food" (cut cakes, sticky bean buns and sticky rice cakes). "Ginger Bean Sprout House" is the most famous cake cutting shop. His cut cake is one meter in diameter and half a foot thick. In the middle is a "five flowers and three layers" big kidney bean, which is yellow in color and delicious. If you bite it, you will lose your teeth. ■
