Pandan Tāngyuán is a variation that incorporates pandan leaf extract into the sticky rice dough, giving the rice balls a vibrant green color and a fragrant aroma. The filling can still be traditional or you can experiment with pandan-flavored fillings like coconut or pandan custard. The Pandan Tāngyuán can be served in a pandan-infused syrup or even in a pandan-flavored broth for a unique and refreshing dessert that showcases the flavors of Southeast Asia.
