The second stop of the May Day holiday tour of Tianjin is from the South Great Mosque, passing the northwest corner, and heading east along Beima Road to the northeast corner of the Erduoyan Fried Cake Shop. The name of Erduoyan Fried Cake comes from the place. Erduoyan Fried Cake Shop was originally located at the west entrance of Erduoyan Hutong, Beimenwai Street, Hongqiao District, Tianjin. It is a few low-rise storefronts facing west and east, with blue doors and windows, no seats, and only window sales. There are two large iron pots and several large dough jars inside. Homemade bean paste fillings are also made indoors. Fried cakes are wrapped, fried, and sold on the spot. There are always people queuing outside the window. The fried cake has a red shell and purple-black bean paste. The shell of the fried cake just out of the pot is crispy. When you bite it, the click sound and the soft, glutinous, and sweet taste are memorable. Erduoyan Hutong is also famous for its fried cakes. Erduoyan Hutong is a 100-meter-long north-south alley connecting Beimalu to Guiyi Street. In the middle of the alley, there is a 50-meter-long west-facing alley. To the right of the west exit of the alley is Erduoyan Fried Cake Shop. More than 20 years ago, when Beimenwai Street was widened and demolished, Erduoyan Fried Cake Shop moved to the northeast corner. Now Erduoyan Fried Cake has many branches. Fried cakes are still fried in stores, but the dough is factory-produced. There are many more flavors. Purple sweet potatoes and chocolate have also become fillings for fried cakes. With the development of the times, people's tastes have also kept up with the pace of the times.
