Yunnan Crossing-the-Bridge Noodles (Guò Qiáo Mǐ Xiàn)

The most famous dish of Yunnan province comes with a legend: a scholar's devoted wife carried broth across a long bridge to his island study each day. Discovering that a thick layer of chicken fat kept the soup scalding hot for the entire journey, she began adding raw ingredients tableside so they could cook in the still-boiling broth on arrival. Whether the story is true or embellished, the technique is sound — a deep bowl of intensely flavored, fat-sealed chicken stock arrives at the table at a rolling internal temperature, and diners lower paper-thin slices of raw chicken, pork, and vegetables into it in a particular sequence, watching them turn opaque within seconds. The rice noodles go in last. This is one of China's great theatrical eating experiences and one of its oldest recorded noodle traditions.

Serves: 2

Ingredients

For the broth:

• 1 whole free-range chicken carcass plus 2 bone-in legs
• 100 g (3½ oz) Yunnan-style ham (or prosciutto), cut into 2 pieces
• 8 dried shiitake mushrooms
• 2 litres (8½ cups) cold water
• 4 slices fresh ginger
• 2 tsp salt
• 30 g (2 tbsp) rendered chicken fat or lard (to seal the surface)

For the toppings (per bowl):

• 60 g (2 oz) chicken breast, sliced paper-thin (partially freeze for easier slicing)
• 60 g (2 oz) pork loin, sliced paper-thin
• 4 raw prawns, shelled and butterflied
• 2 quail eggs (or 1 egg yolk)
• A small handful of baby spinach or chrysanthemum greens
• 2–3 slices of wood-ear mushroom, blanched
• 200 g (7 oz) fresh Yunnan rice noodles (or soaked dried rice vermicelli)
• Sliced spring onion and white pepper to finish

Instructions

1. Make the broth: combine chicken carcass, legs, ham, shiitakes, ginger, and cold water in a large pot. Bring slowly to a boil over medium heat, skimming constantly. Reduce to a bare simmer and cook uncovered for 3 hours.
2. Strain through a fine-mesh sieve. Discard solids. Season with salt. The broth should be pale gold and very clear. Return to a clean pot.
3. Prepare all toppings and arrange each person's ingredients on small plates before serving — the experience depends on speed.
4. When ready to eat, bring the broth to a vigorous boil. Ladle it into the deepest bowls you own (pre-warm them with boiling water first). Add the rendered chicken fat to each bowl — it will form a shimmering, insulating layer.
5. Working quickly, lower the thinest slices of meat into each bowl first. They will begin cooking immediately. After 30 seconds, add the prawns and quail egg. After another 30 seconds, add the greens and mushrooms.
6. Finally add the rice noodles and gently push everything below the surface. Season with white pepper and spring onion. Eat immediately.

Cook's Notes: The fat seal is not optional — it is the engineering principle that makes the dish work. Traditional Yunnan ham (xuanwei ham) is cured and quite salty; reduce added salt if you use it. Slicing meat paper-thin is easiest when the pieces are half-frozen. Leftover broth freezes beautifully for up to three months.
