Bún cá Sứa

Bun ca Sua is a light, fragrant Vietnamese rice noodle soup from Hanoi's Old Quarter, distinguished by its clear fish-and-jellyfish broth and the silky rice vermicelli that form its base. The broth is built from simmered jellyfish and freshwater fish, giving it a clean, ocean-brine quality rather than the pork or beef backbone of more common Vietnamese noodle soups. The bowl is assembled tableside: a nest of white rice noodles is first covered with sliced fresh herbs - tarragon, saw-leaf herb, and banana flower - then topped with fried fish cakes and a generous handful of bean sprouts. The hot broth is poured over at the last moment, barely cooking the herbs and keeping the sprouts crunchy. Lime wedges, fresh chili, and a small dish of hoisin-based dipping sauce complete the condiments. Street vendors in Hanoi's Old Quarter famously serve it from dawn, making it a quintessential early-morning Hanoi breakfast.

Bún cá Sứa is a specialty of Nha Trang, a coastal city in central Vietnam renowned for its seafood. The dish reflects the region's long-standing fishing traditions, combining freshwater or marine fish with jellyfish - an ingredient that has been used in Vietnamese coastal cooking for generations, though the precise origins of this particular noodle soup are not extensively documented.

The defining feature of bún cá sứa is the contrast between tender fish and the crunchy, slightly chewy texture of jellyfish, served in a savory, clear broth over rice vermicelli. It is a beloved local breakfast and lunch option in Nha Trang, often garnished with fresh herbs, bean sprouts, and lime, and it exemplifies the Vietnamese culinary practice of incorporating diverse seafood into everyday noodle dishes.
