A Hanoi vermicelli soup built on Muscovy duck in a clear, clean broth. Ngan, the Muscovy duck, has firmer, leaner, more flavorful flesh than common duck, and here it is simmered into a light golden broth, sliced, and laid over rice vermicelli with herbs. It is a humble, everyday northern noodle bowl — a fixture of small Hanoi eateries at lunch — and is distinguished from the better-known sour-bamboo duck noodle by its plain, unsoured broth that lets the duck itself lead.
Bun ngan belongs to Hanoi and the northern delta, part of the city's broad family of clear-broth poultry vermicelli soups. The Muscovy duck, called ngan in Vietnamese and known in Chinese as the foreign duck for its New World origin, is favored in the north for being meatier and less fatty than the common duck, holding up well to simmering. The dish is unpretentious lunch-counter food rather than a documented historic specialty; its identity rests on the choice of bird and on keeping the broth clean and clear rather than dressing it up.
A bowl of soft rice vermicelli under slices of Muscovy duck, in a broth that is clear and golden and tastes purely of the bird. The duck is firmer and chewier than ordinary duck, with a cleaner, less greasy flavor; the broth is light, savory, gently sweet from simmered bones, with no sourness to mask it. Scallion, herbs, and a squeeze of lime go on at the table, and a sharp ginger-fish-sauce dip on the side carries the dipped pieces of duck.
The whole point is a clear broth, which takes discipline. The duck is parboiled first and the water discarded to remove scum and excess fat; only then does it go into the real pot, where it simmers at a bare tremble — a hard boil clouds the broth. Charred ginger and shallot are added for depth and to round out the slightly gamey edge Muscovy duck can carry. The bird is pulled the moment it is just cooked so the meat stays firm rather than stringy, then sliced; the fat is skimmed to keep the bowl clean.
Variations
The clear-broth version here is the plain everyday form; the same duck is also cooked with sour bamboo shoots, which makes it the close cousin of bun mang vit but with Muscovy in place of common duck. Some Hanoi shops add a few cubes of congealed duck blood or serve the duck off the bone as a separate plate with the dipping sauce. A drizzle of duck fat with fried shallot is a common enrichment for those who want a heavier bowl.

- 210 min
Parboil the duck briefly, then discard the water and rinse off the scum.

Char ginger and shallot over a flame until fragrant and blackened at the edges.
- 460 min
Simmer the duck with the charred aromatics in fresh water at a bare tremble, skimming, until just cooked.

Remove the duck, let it cool, then slice or shred the meat; keep the broth simmering and season with fish sauce and salt.
Watch outPull the duck the moment it's just cooked; leave it in and the meat turns stringy instead of staying firm and sliceable.
