Combine the soy sauce, sweet bean sauce, shaoxing wine, and five-spice powder in a nonmetallic bowl, and then apply to the lamb chops, with a little salt to taste, if you wish. Mix well and leave to marinate for at least 30 minutes
Meanwhile, finely slice the scallion greens. Tear the coriander leaves for the garnish; set aside
Heat a grill pan over a high flame until very hot. Brush the lamb chops with the oil and cook for 2-3 minutes, then flip over and scatter generously with cumin and chili flakes. Continue cooking for 2-3 minutes longer (2 minutes on each side if you like your meat pink and juicy like I do), scattering with scallions when nearly done
Place the chops on a serving dish, sprinkle with a little sesame oil (a couple of teaspoons). and scatter with coriander leaves
