Gēng (Chinese: 羹; pinyin: gēng; Wade–Giles: keng1; Pe̍h-ōe-jī: keⁿ / kiⁿ) is type of thick or clear soup found in Chinese cuisine. Its thickening agent is usually starch which makes the soup translucent and smooth. Many soups can be cooked in this way, such as expensive shark fin soup, Madame Song's fish soup (宋嫂魚羹), and corn soup. Source: Wikipedia (en)
