For a unique and savory twist, try making cheese-filled Tāngyuán. This recipe suggests using a combination of cream cheese and shredded cheddar cheese as the filling for the sticky rice balls. The cheese filling adds a creamy and slightly salty flavor to the Tāngyuán, creating a delightful contrast to the sweetness of the dough. Serve them with a sprinkle of grated Parmesan cheese or a drizzle of honey for a delicious and cheesy treat.
