Bún bò Huế is a noodle dish utilizing a round, wheat noodle as its base. The broth is rich and ingredients include thinly sliced beef shank, chunks of oxtail and pig's knuckles. It can also include cubes of congealed pig blood, which most restaurants will omit if you ask. This bowl of noodles is served with fresh cilantro, scallions, raw onion slices, shredded banana blossoms, red cabbage, mint, basil, perilla and a bunch of Vietnamese herbs such as rau răm (Vietnamese coriander) and ngò gai (sawtooth herb). Bean sprouts are sometimes offered as well.
