This recipe for traditional Tāngyuán is a classic Chinese dessert made with sticky rice flour and filled with sweet fillings like black sesame or red bean paste. Using a food processor makes the process of making the dough much easier and faster. The sticky rice flour is pulsed with water in the food processor until a smooth dough is formed. The dough is then divided into small portions, filled with the desired filling, and rolled into balls. The Tāngyuán are then cooked in boiling water until they float to the surface. Serve these delicious sticky rice balls in a sweet ginger syrup for a delightful dessert.
