　　Quankou Grey Tofu

　　Quankou Grey Tofu is made from locally grown soybeans in northern Dejiang, selected for their uniform size, absence of impurities, insect damage, or mold. The production process mainly includes: soaking the beans (in warm water at around 30°C), grinding (using a stone mill), filtering (with a sieve, commonly known as the tofu cloth), boiling the slurry (in an open cauldron), refining (filtering again with a fine mesh), coagulating (adding brine while controlling temperature and concentration), shaping (pressing out the whey), cutting (into small pieces), stir-frying (using glutinous rice straw ash or soybean stalk ash, with controlled temperature and intensity), and packaging. Grey tofu is mainly used in soups and hot pot dishes (added to the main ingredients after they are well-cooked, then simmered over low heat for 3–5 minutes). It is tender, sweet, smooth, and has a pure flavor that lingers on the palate.
