Cooking cakes in yanggu county are recorded in The Water Margin. In those days, the husband and wife shop opened by Mr. Wu Dalang and Ms. Pan Jinlian mainly engaged in cooking cakes. In the 26th chapter of The Water Margin (the 25th chapter of the golden edition), Uncle He Jiu went to burn paper money for Wu Da, saying, "I bought a cage cake from Dalang the day before yesterday, but I didn't get the money back, so I specially burned this strange paper for Dalang." Jin Shengtan commented: "From the day I read it to the day I caught him, it meant that the word" long "was different from" cooking cake ",so I didn't want to bring it up here. Things are different, and people have to cry. " Wu Da is inseparable from cooking cakes. When it comes to Wu Da, you can't help but think of cooking cakes. So, what exactly is a cooking cake? People's Literature Publishing House published a book entitled "Talking about the Water Margin" in 2: "Some people may think that it is Shandong pancakes or today's scones and biscuits, but it is wrong. Cookies are not pancakes, but pancakes are stalls; It is not scones or biscuits. scones and biscuits are baked and branded, while cooking cakes are steamed. It is actually a snack in the south, similar to Fujian's light cakes. "
