The soup's roots trace back over 1,400 years to Nanjing's imperial duck-cuisine culture, but only reached its street-food form in the late 1940s.
A clear duck broth is filled with cubes of duck blood curd, glass vermicelli, and duck offal, often finished with fried tofu puffs, scallion, and chili oil.
