Nanjing-Duck blood vermicelli soup

It seems that only Nanjing can make vermicelli soup with duck blood. As far as I know, there are two best, one is in Zhenghong Street (a famous shopping street in Nanjing, everyone knows it), and the other is in the alley behind the Gulou Telecommunications Bureau. Shops are small, and there is a big pot in front of the store, in which duck soup keeps rolling. Put the prepared vermicelli into the soup, slightly hot, put it into a bowl, pour the soup, and put the ingredients: duck blood, duck intestines, duck liver, mustard tuber, coriander and spicy oil. The master of the operation is extremely quick, and the whole process takes less than a minute. Even so, you often have to wait in line and stand by the pot to ensure the first hand. Standing by the pot, the special and fragrant smell of duck's blood and duck's intestines is warm and hot, which can arouse your appetite. Duck blood soup is a low-grade snack among the people, and the current price is only three or four yuan. The taste of soup is the most important, probably with a secret recipe, very strong.
