For a unique twist, try making Cheese-filled Tāngyuán. Instead of sweet fillings, you can stuff the rice balls with cheese like cream cheese, mozzarella, or even blue cheese. The cheese-filled Tāngyuán can be served in a savory broth or even in a tomato sauce for a fusion of flavors. The combination of the chewy rice balls and the gooey melted cheese creates a savory and indulgent treat that will surprise and delight your taste buds.
