📝 About This Recipe

Tracing its roots back to the Yuan Dynasty, Instant-Boiled Mutton (Shuàn Yángròu) is the soul of Beijing's winter culinary tradition. Unlike its spicy Sichuan cousin, this Northern classic uses a clear, minimalist broth to highlight the natural sweetness of paper-thin, high-quality lamb. The experience is defined by the 'velvet' texture of the meat and a rich, nutty sesame dipping sauce that creates a warming, communal masterpiece.

🥗 Ingredients

The Meat & Proteins

  • 1.5 lbs High-quality boneless lamb leg or shoulder (partially frozen for easier slicing, or pre-sliced 'hot pot' lamb)
  • 1 block Firm Tofu (cut into 1-inch cubes)
  • 1 block Frozen Tofu (thawed and squeezed of excess water to better absorb broth)

The Clear Broth Base

  • 8-10 cups Water (enough to fill the hot pot 2/3 full)
  • 5-6 slices Ginger
  • 2 stalks Scallions (cut into 2-inch lengths)
  • 1 tablespoon Dried Goji Berries (for a hint of sweetness)
  • 2-3 pieces Dried Shiitake Mushrooms (optional, for subtle umami)

Essential Dipping Sauce

  • 1/2 cup Chinese Sesame Paste (pure toasted sesame paste, not tahini)
  • 1-2 cubes Fermented Red Bean Curd (mashed with a little of its own juice)
  • 1 tablespoon Leek Flower Sauce (salty and pungent, essential for authenticity)
  • 1 tablespoon Light Soy Sauce
  • 1 teaspoon Toasted Sesame Oil
  • to taste Chili Oil (optional)

Vegetables & Starches

  • 1 head Napa Cabbage (hand-torn into bite-sized pieces)
  • 1 bunch Crown Daisy (Tong Ho) or Spinach (washed and trimmed)
  • 1 bundle Cellophane Noodles (Glass Noodles) (soaked in warm water for 15 minutes)

👨‍🍳 Instructions

  1. 1

    Prepare the lamb: If using a whole cut, freeze the meat for 1-2 hours until firm but not rock-hard. Using a very sharp knife, slice the lamb across the grain into paper-thin ribbons that curl naturally.

  2. 2

    Arrange the sliced lamb on large chilled platters in a single layer or slightly overlapping. Keep refrigerated until the moment of serving to maintain texture.

  3. 3

    Make the base sauce: In a medium bowl, start with the sesame paste. Slowly add warm water or room temperature broth one tablespoon at a time, whisking constantly until the paste reaches the consistency of heavy cream.

  4. 4

    Incorporate the 'Beijing Trinity': Stir the mashed fermented bean curd and leek flower sauce into the thinned sesame paste until smooth. Add soy sauce and sesame oil.

  5. 5

    Prepare the aromatics: Slice the ginger, cut the scallions into sections, and rinse the goji berries. These will provide a clean, fragrant background for the meat.

  6. 6

    Prepare the vegetables: Wash the Napa cabbage and greens thoroughly. Cut the tofu into uniform cubes. Arrange all side ingredients on separate plates for communal access.

  7. 7

    Set up the pot: If using a traditional charcoal copper pot, light the coals outside before bringing it in. For electric or butane versions, simply place the pot in the center of the table.

  8. 8

    Fill the pot with the water, ginger, scallions, goji berries, and mushrooms. Bring the liquid to a rolling boil.

  9. 9

    Once boiling, give each guest their own bowl of the prepared sesame dipping sauce. Garnish the sauce bowls with chopped cilantro or scallions if desired.

  10. 10

    Begin the feast: Using chopsticks, pick up a slice of lamb and submerge it in the boiling broth. Swish it back and forth for 10-15 seconds until it just turns opaque and pale pink.

  11. 11

    Immediately dip the cooked lamb into your sauce bowl, coating it thoroughly, and enjoy while hot.

  12. 12

    Gradually add the tofu and cabbage to the pot. These take longer to cook and will absorb the flavors of the lamb as the meal progresses.

  13. 13

    Final Flourish: Once the meat and vegetables are finished, add the soaked glass noodles to the now-rich broth for a final, comforting slurp to end the meal.

💡 Chef's Tips

For the most authentic flavor, seek out 'Leek Flower Sauce' at an Asian grocer; its unique salty-floral profile is irreplaceable. If slicing meat yourself, ensure you cut against the grain to prevent the lamb from being chewy. Do not overcook the lamb! It only takes seconds; leaving it in the pot too long will make it tough and dry. Add ingredients to the pot in batches to keep the water at a steady boil; adding too much at once will drop the temperature and ruin the 'instant' effect.

🍽️ Serving Suggestions

Pair with 'Shao Bing' (Beijing sesame flatbreads) to stuff with cooked lamb and sauce. Serve with 'Laba Garlic' (vinegar-preserved green garlic) to provide a sharp, acidic contrast to the rich lamb. Enjoy with a chilled glass of Yanjing Beer or a pot of strong Jasmine tea to cleanse the palate. Finish the meal by drinking a small bowl of the remaining broth, which will have become a rich, flavorful soup.
