Beef covered cakes began in the Qing Dynasty. According to legend, Emperor Jiaqing passed Baoding on his southern tour. When he heard a strange smell, he perked up and asked, "What is this smell?" Left and right answer: "beef covered cake." Jiaqing was very happy when the magistrate was about to present the beef covered cake. After eating it, he praised: "color, fragrance and taste." Since then, beef covered cakes have become a delicacy for all governors to entertain guests. Baijiagai cake inherited the advantages of beef gai cake, and added its own characteristics to carry forward. After the efforts of Bai's descendants, it is unique in the catering industry. From the earliest Nanguan Nanhepo store, it has developed into a chain catering company with six branches, and registered the trademark intellectual property right-"Baijialaohao" in the State Administration for Industry and Commerce. Baijiazhao cake takes Inner Mongolia beef as raw material and its ribs as main material. It is made by secret processing with century-old soup. The finished dish is ruddy in color, tender in meat, fragrant, more fragrant to chew and delicious. Lotus leaf cake is soft and delicious. Pour a spoonful of century-old soup on it and sprinkle with leeks. It tastes delicious. Even many foreign businessmen have been here, and they are full of praise after eating.
