Tang Yuan (Sweet Rice Balls)

Tang yuan are sweet glutinous-rice flour balls, their round form carrying a weight of ritual significance in Chinese culture — the spherical shape and the word yuan (meaning round, complete) evoke family reunion and the full moon, making them the canonical food of the Lantern Festival (the 15th day of the first lunar month) and of the Winter Solstice (Dongzhi), when families gather to eat them together.

The outer wrapper is made from glutinous (sticky) rice flour kneaded with water to a smooth, pliable dough — the texture when cooked is soft, slightly resistant, and chewy in a way that regular rice flour would not be. The filling is a thick, sweetened paste, most commonly ground black sesame mixed with lard and sugar (the Ningbo style, considered the classic), or peanut paste, red bean, lotus paste, or taro. The filling is sealed inside the wrapper, rolled smooth, and the ball is briefly boiled in water until it floats.

Served in a bowl with sweet syrup: a ginger syrup (thin, mildly spiced) is the traditional pairing; osmanthus (gui hua) syrup is the Hangzhou and Suzhou preference; sweet fermented rice wine (jiu niang) provides a slightly alcoholic, floral version. The broth is not discarded — it is drunk from the bowl.

Commercially, Tang yuan are widely available frozen across China year-round. The freshly-made versions — particularly in Ningbo, where the black-sesame style claims precedence — are softer and less dense than the frozen product.
