Step 1: Prepare the Marinade

1. In a large bowl, combine soy sauce, Shaoxing wine, vegetable oil, honey, garlic, ginger, salt, and black pepper.
2. Add the lamb cubes, ensuring each piece is well-coated. Cover and marinate for at least 2 hours (overnight for best flavor).

Step 2: Prepare the Skewers

1. If using bamboo skewers, soak them in water for 30 minutes to prevent burning.
2. Thread 4-5 pieces of marinated lamb onto each skewer, leaving a small gap between each piece.

Step 3: Prepare the Grill

1. Heat a charcoal grill until the coals are covered in white ash. Arrange for medium-high heat.
2. Lightly oil the grill grates to prevent sticking.

Step 4: Grill the Lamb Skewers

1. Place the skewers directly over the heat and grill for 6-8 minutes, turning every 30 seconds.
2. Sprinkle the spice mix over the lamb while grilling to enhance the flavor.
3. Cook until the lamb is slightly charred but juicy inside.

Step 5: Serve & Enjoy

1. Remove from heat and let the skewers rest for 2 minutes.
2. Garnish with chopped green onions and sesame seeds.
3. Serve hot with a side of cucumber salad, scallion pancakes, or steamed rice.
