Classic Tāngyuán is a traditional Chinese dessert made from sticky rice flour. These small glutinous rice balls are typically filled with sweet fillings like black sesame, red bean paste, or peanut butter. The rice balls are cooked in boiling water until they float to the surface, and then served in a sweet syrup made from rock sugar and water. The chewy texture of the rice balls combined with the sweet and fragrant filling makes for a delightful treat.
