Shanghai leishayuan

Shayuan is one of the famous flavor spots of Qiaojiazha Dim Sum Shop in Shanghai, which has a history of more than 70 years. According to legend, at the end of Qing Dynasty, there was an old lady named Lei in Sanpailou, Shanghai. In order to make the dumplings easy to store and carry, she pioneered the method of rolling white powder on the surface of cooked dumplings. Later generations named the dumplings as rolling sand balls in memory of her. The sand-grinding balls operated by Qiaojiazha Dim Sum Shop are made by cooking red beans in Dahongpao, Chongming County, grinding them into sand, and drying them into purple powder. Then, the glutinous rice dumplings with fresh meat, bean paste, sesame seeds and other fillings are cooked, drained and rolled with a layer of bean paste powder. This kind of dumpling is colorful and fragrant, has a strong red bean flavor when eaten hot, and is soft, waxy and refreshing, and easy to carry, which has always been popular with tourists.
