This rich Chinese meat sauce is deeply savory, fragrant with whole spices, and packed with mushrooms, fermented black beans, and aromatics. Spoon it over noodles, rice, tofu, or steamed vegetables for a bold, restaurant-style topping you can make ahead.
Place a clean, dry wok over medium-low heat. Add the neutral oil, star anise, cinnamon stick, bay leaves, Sichuan peppercorns, and black cardamom pods. Gently heat for about 10 minutes, adjusting the heat as needed so the spices become fragrant without burning. Turn off the heat and let the oil infuse while you prepare the remaining ingredients.
Strain the infused oil back into the wok and discard the whole spices. Set the wok over high heat, then add the ginger, garlic, shallot, the white parts of the scallions, and the Thai chilies. Stir-fry for 1 to 2 minutes, until aromatic and just lightly golden.
Add the ground meat and break it up with a spatula. Cook until browned and lightly crisp at the edges. Stir in the fermented black beans and chopped mushrooms, then continue cooking until the mushrooms release their moisture and the mixture becomes dry and lightly caramelized.
Reduce the heat to medium. Add the hoisin sauce, light soy sauce, oyster sauce, Shaoxing wine, dark soy sauce, and sesame oil. Stir well and simmer for about 10 minutes, stirring occasionally, until the sauce is glossy and the flavors are fully blended.
Stir in the green parts of the scallions and cook for 2 more minutes. Remove from the heat, fold in the toasted sesame seeds, and serve warm or let cool before storing.
Ground pork is the classic choice, but ground beef or chicken also works well. Cook the mushrooms until their liquid has fully evaporated for the deepest flavor. Store the sauce in an airtight container in the refrigerator for up to 5 days, or freeze for up to 2 months.
