Velvet the beef: In a bowl, mix sliced beef with Shaoxing wine, soy sauce, cornflour, bicarb, oil, salt and white pepper. Set aside to marinate for 15 minutes.
Make the sauce: Combine light soy, dark soy, rice wine vinegar, brown sugar, honey, water and cracked black pepper. Set aside.
Sear the beef: Heat a wok over high heat with oil. Add the beef in a single layer and leave it untouched to develop charred edges. Once just cooked, remove from the wok.
Cook the aromatics & greens: In the same pan, add onion, spring onion, dried chillies and garlic. Cook until fragrant, then add gai lan and toss until just tender.
Bring it together: Return the beef to the wok, pour in the sauce and add more spring onion. Toss until the sauce thickens slightly and coats everything.
Finish: Stir through a knob of butter for extra gloss and richness.
Serve with rice and fried shallots
