'red bean soup, red bean sand') is a popular Chinese dish served in Mainland China, Taiwan, Hong Kong, Macau, and places with Chinese diaspora. It is categorized as a tang shui 糖水 (pinyin: táng shuǐ) (literally translated as sugar water) or sweet soup. It is often served cold during the summer, and hot in the winter. Leftover red bean soup can also be frozen to make ice pops and is a popular dessert.
In Cantonese cuisine, a red bean soup made from rock sugar, sun-dried tangerine peels, and lotus seeds is commonly served as a dessert at the end of a restaurant or banquet meal. Common variations include the addition of ingredients such as sago (西米, pinyin: xī mi), tapioca, coconut milk, ice cream, glutinous rice balls, or purple rice. The two types of sugar used interchangeably are rock sugar and sliced sugar (片糖).
Unsweetened red bean porridge made with red beans and rice is eaten across China and East Asia. Japan has a similar variant called Shiruko. It is called hóngdòuzhōu (红豆粥) in Chinese, patjuk (팥죽) in Korean, and azukigayu (小豆粥) in Japanese.
