Lamb Skewers (Chuan'r)

Cut the lamb shoulder into uniform 2-3 cm cubes.

In a large bowl, combine the lamb shoulder cubes with light soy sauce, Shaoxing wine, sesame oil, grated ginger, minced garlic, cumin powder, chili flakes, Sichuan peppercorn powder, white pepper, and salt. Mix thoroughly to ensure all lamb pieces are coated.

Cover the bowl and refrigerate the marinated lamb for at least 2 hours, or preferably overnight, to allow the flavors to meld.
