Chongqing's big dumplings are soaked in glutinous rice for three days, ground into rice paste with a stone mill, wrapped in white cloth, and drained. In this way, the main ingredients of glutinous rice balls are ready. Then there is the stuffing of glutinous rice balls. In Chongqing, we usually make sesame and peanut mixed stuffing. First, we fry and grind sesame seeds and peanuts, then add winter melon sugar, white sugar and orange cake rock sugar, and then add some orange peel and stir well. In the future, you can knead the stuffing made from jiaozi bag and cook it in a pot. When it is cooked, you can eat it. This is the practice of Chongqing Datang Yuan.
