We went to Liuyin Street, where we used to live, when the father's unit allocated a house in the large yard on the north side of the campus of the 13th Middle School today, which is part of the Qingwang Mansion, which is estimated to be the place where the housekeepers live, and the side door is facing the Prince Gong Mansion. After watching Liuyin Street, he continued to bring his father to his long-lost Yao Ji fried liver, a small bowl of fried liver, a braised boiled fire, three buns, a plate of drying cucumber, a plate of fried enema. Sleeves, neck stretched, big mouth, big fast. Fried liver and buns will not say, this is the signature of Yao Ji, only said that this braised boiling fire. From the perspective of modern human health, braised cooking does not meet this trend, and only exists in Beijing and limited surrounding areas, regardless of taste or material, it is difficult to impress the deep accumulation of food in the south, especially in Jiangsu, Zhejiang and Huguang. In the eyes of Beijingers, Yao Ji, Xiaochang Chen, Beixinqiao are the most authentic "pig sewer" snack bars, and a door frame alley has risen in the past few years. And attractions such as Qianmen Dashilan Wangfujing Luguxiang along the street of the braised boiling shop, no matter how eye-catching the store label, the old Beijingers will never enter, even when they walk to the door, they frown. The so-called braised boiling fire is simply to cut the fried tofu, fire spoon into a wedge-shaped block, and then pour into the long-term boiling of the strong fragrant raw soup, so that the small intestine and pig lungs like a sponge to suck the juice, creating a unique taste. Braised boiling fire, pay attention to the taste is thick but not greasy. (It can't be greasy at all, but with the green mouth greasy drying cucumber or mustard pier will greatly improve the uncomfortable taste.) Fire, pay attention to the transparent but not sticky, soaked by the thick old soup, taste but can not have tenacity, so-called non-stick mouth, non-stick teeth. Small intestine, pay attention to fat but not greasy, the entrance smooth and instant, chewing teeth and cheeks left incense.
