Chatang (茶汤; pinyin: chátāng; literally "tea soup") or seasoned flour mush is a traditional gruel common to both Beijing cuisine and Tianjin cuisine, and often sold as a snack on the street. It is made from sorghum flour and/or broomcorn millet and/or proso millet flour and glutinous millet flour. The Chinese name is figurative, not literal, as there is neither any tea nor any soup in this dish.The dish is prepared in two steps.
