Method
- Marinate the beef. In a large bowl, combine the beef with the bicarbonate of soda, light and dark soy sauces, Shaoxing wine, cornflour, sesame oil, and pepper. Toss well to coat and set aside for 15–20 minutes while you prepare the remaining ingredients.
- Make the sauce. In a small bowl, whisk together the oyster sauce, dark soy sauce, sugar, black pepper, beef stock, and cornflour/water mix until smooth.
- Stir-fry the beef. Heat a large deep heavy-based pan over high heat. Add 1 tablespoon of the oil and cook half the beef for 1–2 minutes until browned. Transfer to a plate and repeat with the remaining beef and oil.
- Add the vegetables. To the same pan, add the onion and garlic. Cook, stirring, for 1 minute until fragrant. Add the choy sum and toss for another 1–2 minutes until just wilted.
- Combine everything. Return the beef to the pan. Add the noodles. Pour in the black pepper sauce and toss using tongs for 2–3 minutes until glossy and heated through.
- Serve. Divide among four bowls and finish with extra cracked black pepper, if using.

Notes
You can substitute the rump steak with sirloin, porterhouse, or New York strip. For chuck or oyster blade steak, use the traditional velveting method: sprinkle beef with 1 teaspoon bicarbonate of soda per 500 g, mix, rest for 20 minutes, rinse thoroughly under cold water, drain, pat dry, then combine with marinade ingredients. The bicarbonate of soda ratio is 1/4 teaspoon per 500 g beef for tender results. Spice levels can be adjusted: 1/2 teaspoon pepper for mild, 1 teaspoon for medium, and 1 tablespoon for bold. You can use any noodles like udon, ramen, thin egg noodles, or rice noodles. Prepare noodles according to package directions, ensuring they are not overcooked. A quick method for Hokkien or udon noodles is to pierce the bag, microwave for 1-2 minutes, then separate under cold running water. If using dried noodles, approximately 250-300 g uncooked will serve four.
