At that time, there were many wealthy merchants living in Xiguan, Guangzhou. In order to attract customers, restaurants and restaurants competed for innovation. One day, Chen Weiqing, an old cake maker in Lianxiang Building, was drinking lotus seed syrup. He had an idea and tried to make cake filling with lotus seeds. He washed the lotus seeds and removed their hearts. He put them in a copper pot and boiled them continuously. Then he added sugar and peanut oil. This was the first attempt to make lotus paste stuffing. Unfortunately, lotus paste made in this way has a bitter taste and a poor flavor. After repeated tests, Master Chen has developed a new process to remove the lotus seed peel with water, which makes lotus paste retain the fragrance of lotus seed and remove the bitter taste of lotus seed peel. It is golden in color, smooth in texture and rich in lotus fragrance. As soon as the lotus paste pastry with unique flavor was introduced, it was widely praised and sought after by diners. Gradually, the lotus paste food in Lotus Fragrance House entered thousands of households, and Lotus Fragrance House also won the reputation of "the first lotus paste". According to the memory of the old baker, there is a saying in the cake industry in Guangdong and Hong Kong: "Only with Lotus Fragrance Pavilion and Lotus Seed, can lotus seed moon cakes be created".
