Mochi Tāngyuán is a fusion recipe that combines the Chinese Tāngyuán with the Japanese mochi. The dough is made from glutinous rice flour and filled with a variety of sweet fillings, such as red bean paste, matcha, or fruit. The rice balls are then coated with a layer of powdered sugar or kinako (roasted soybean flour). This recipe is a delightful fusion of two beloved Asian desserts.
