Red bean paste is a classic filling for Tāngyuán and is loved for its sweet and creamy texture. These sticky rice balls are filled with red bean paste, creating a delightful combination of flavors. The dough is made with glutinous rice flour and rolled into small balls before being filled with the red bean paste. Boil them until they become soft and chewy, and serve them in a warm ginger syrup for a traditional and comforting dessert.
