What goes into a bowl
Duck blood vermicelli soup brings duck blood, vermicelli and duck offal together in hot broth, offering another introduction to Nanjing's duck dishes. Duck blood is an animal blood product set into soft, smooth blocks. Vermicelli consists of thin starch noodles that become soft and slippery when cooked. Common additions include duck liver, intestines, gizzard and fried tofu puffs, with chopped spring onion, coriander and other garnishes. The light and dark pieces in the bowl are different ingredients; ask the server to identify them when ordering for the first time.
The dish combines contrasting textures: soft duck blood, firm gizzard, springy intestines and finer-textured liver. Tofu puffs have porous interiors that readily absorb broth. The selection of offal, ingredients used in the vermicelli and broth differ between shops. Ask what “the full set” or “extra toppings” includes, and do not judge portion size from a photograph alone.
From duck blood soup to vermicelli soup
Material compiled by Nanjing's local chronicles office records duck blood soup in descriptions of local snacks as early as the 1940s. Stalls once sold duck blood and offal soups around Jiankang Road and Shengzhou Road in the south of the city. Today's version, with vermicelli and tofu puffs, both continues and changes that earlier soup. Describing a modern bowl as an unchanged ancient recipe obscures this development.
Several stories describe who first combined duck blood and vermicelli, but they do not establish a single inventor. For visitors, it is more useful to identify the ingredients and preparation in front of them. Duck offal usually needs separate preparation, and the vermicelli is cooked before being combined with broth and other ingredients. Fast service at the counter does not mean every ingredient was prepared at the last moment.
Taste the broth before seasoning
Start with a small sip of plain broth to assess its savouriness, saltiness and pepper, then add a little chilli oil or fragrant vinegar if wanted. Both change the flavour of the whole bowl, so there is no need to add a large amount on a first try. Broth inside tofu puffs may be very hot; splitting a puff with chopsticks or waiting briefly is safer than putting a whole one straight into your mouth.
Vermicelli gives the soup the role of a staple meal, but portions and toppings vary by shop. For a light meal, look at the bowl size before deciding whether to add a baked flatbread, buns or similar food. For a taste, a basic bowl makes the ingredients easier to identify. Like salted duck, the dish centres on duck, but the way it is eaten differs. Choose according to your preference for hot soup, offal or pieces of meat.
Explain dietary restrictions before ordering
If you do not eat animal blood or offal, specify which ingredients you want removed before paying rather than simply saying “no meat”. Even without duck blood and offal, the broth may contain duck or other animal ingredients, so removing them does not make the dish vegetarian. If you want to keep the vermicelli but reduce a particular type of offal, ask whether this is possible. Ingredients already mixed or portioned in advance may not be separable.
Tofu puffs involve soy, and sesame oil involves sesame. The exact ingredients in seasonings and vermicelli may also differ. If you have food allergies or strict dietary restrictions, show the server the Chinese names of ingredients you need to avoid and check the broth, toppings and contact with utensils. If the shop cannot explain them, choose a meal whose ingredients can be clearly identified. This article does not treat a particular vermicelli recipe or clear-looking broth as a guarantee that a dish is free of allergens.
