Ma Erjia's dumplings are eaten dry in summer, hot soup in winter, and the best is sour soup dumplings. In this bowl of dumplings, dumplings are the supporting role, and the sour soup is the protagonist. With more than 30 years of experience, he has made a sour soup that is sour, spicy and fragrant, not greasy or greasy, enough to open the taste buds of diners. The supporting dumplings contribute to the filling of this delicacy, and the filling of the dumplings needs to be packed into a bag of beef, leeks and spices and beaten until they do not fall apart, so that the cooked dumpling filling is tender and firm. The sour and spicy soup is paired with smooth dumplings, and it will bring a refreshing taste regardless of the season.
