Bún bò Huế is a popular Vietnamese soup containing rice vermicelli (bún), beef (bò) and sometimes pork knuckles and pig blood curds.[1] Huế is a city in central Vietnam associated with the cooking style of the former royal court.[2] The dish has a mix of spicy, salty, and umami flavors. The predominant flavor is that of lemongrass.[3] Compared to phở or bún riêu, the noodles are thicker and more cylindrical.[4] (Wikipedia)
Flavours are layered over each other with boiled pork and beef bones, lemongrass, chili, fermented shrimp paste, and fish sauce used to make the rich, red broth. Immersed in that heady mix is a bed of thick rice noodles (bún) topped with thin slices of boiled beef shank and crab balls. Add a squeeze of lime, some chili paste, and shallot vinegar for an extra kick!
