Guo qiao mi xian (过桥米线, crossing-the-bridge rice noodles) is the signature dish of Yunnan province — a theatrical presentation in which a bowl of boiling-hot, fat-sealed broth is brought to the table accompanied by raw ingredients (sliced pork, chicken, ham, tofu, vegetables, quail eggs) and fresh rice noodles, which the diner adds to the broth in sequence, cooking them at the table. The name refers to the legend of a Yunnan scholar's wife who brought her husband — studying on an island accessible only by a long bridge — her daily meal. She discovered that a thick layer of rendered chicken fat on top of the broth kept it hot enough to cook ingredients upon arrival.
The broth: The most critical element. A truly superior guo qiao mi xian broth is made from slow-simmered bone-in chicken (4-6 hours) and pork bones, producing a rich, clear, gelatinous stock. The rendered chicken fat is skimmed and preserved separately, then added back as a thick insulating layer on top of the broth when served. The broth should be served extremely hot — at near-boiling temperature — in a pre-warmed bowl so that it retains sufficient heat to cook the raw ingredients at the table. The ingredients: Added in order of cooking time required: first — thinly sliced raw pork loin and raw chicken breast (the thinnest possible slices, nearly translucent); then quail eggs; then tofu; then ham slices; then vegetables (pea shoots, etc.); finally — the fresh rice noodles (mi xian). The noodles go in last because they cook within 30-60 seconds. The rice noodles (mi xian): Yunnan rice noodles are round, fresh, and made from rice — distinct from the flat ho fun of Cantonese cooking. They have a firm, slightly chewy texture and are the characteristic noodle of Yunnan.
