Marinate the short ribs: Pat the ribs dry with kitchen paper. Rub evenly with salt, black pepper, garlic powder, cumin, gochugaru (or paprika), and vegetable oil. Marinate in the fridge for at least 2 hours, or overnight for best flavour.
Slow-cook the ribs: Wrap the ribs tightly in 2–3 layers of foil. Bake in a preheated oven at 150°C for 2 hours. After 2 hours, unwrap, increase the oven to 250°C, and roast for 6 minutes until the surface is charred and crispy.* Don’t discard the juices released while roasting the ribs. You can keep them and use as a flavourful sauce. Prepare the noodles: If using packaged Chinese wide noodles, cook according to packet instructions. For the dumpling wrapper hack: defrost dumpling wrappers (if frozen) until soft. Cut in half with scissors, then gently stretch into long, wide noodles (pull slowly to avoid tearing). Cook in boiling water for 3–4 minutes, then transfer immediately to an ice bath to firm up. Blanch the greens: Just before the noodles finish cooking, add pak choi (or other greens) to the boiling water. Cook for 30–60 seconds until bright green, then drain with the noodles.
Assemble the bowl: In a serving bowl, mix soy sauce and black vinegar as the base. Add noodles, blanched greens, and short rib. Top with garlic, spring onion, coriander, sea salt, seasoning powder, chilli flakes, and five-spice.
Finish with hot oil: Heat oil in a pan until smoking. Carefully drizzle over the aromatics and short rib 3 times to release fragrance. Serve immediately and enjoy!
