Traditionally, the Dongzhi Festival is also a time for the family to get together. One activity that occurs during these get togethers (especially in the southern parts of China and in Chinese communities overseas) is the making and eating of tangyuan (湯圓) or balls of glutinuous rice, which symbolize reunion. Tangyuan are made of glutinuous rice flour and sometimes brightly coloured. Each family member receives at least one large tangyuan in addition to several small ones. The flour balls may be plain or stuffed. They are cooked in a sweet soup or savoury broth with both the ball and the soup/broth served in one bowl. It is also often served with a mildly alcoholic unfiltered rice wine containing whole grains of glutinous rice (and often also Sweet Osmanthus flowers), called jiuniang.
Traditionally, we have been eating this tangyuan with roasted peanut/soy bean powder added with sugar. I will see whether I have the energy to go out and buy some later.
