In a large wok over high heat, add the peanut oil and preheat the wok. Meanwhile, combine the star anise, cumin seeds, chile powder, cayenne and Sichuan peppercorns in a spice grinder and pulverize. When the oil is just starting to smoke, add the spices and cook for 1 minute. Add the cabbage and cook, tossing and stirring to coat, just until the cabbage is slightly pliable but still has some crunch, about 5 minutes. Finish with the chile crisp, soy sauce and black vinegar. Adjust for seasoning. Transfer to a platter and garnish as desired with the cilantro and green onions.
