Method
- Heat oil in a wok or wide pan over the highest possible flame. Add the lamb strips in a single layer.
- Sear undisturbed for 90 seconds — the lamb should colour deeply on one side. Toss for another 60 seconds; the lamb should still be pink at the centre.
- Add sliced onion, garlic and ginger. Stir-fry 90 seconds — the onion should soften slightly but still hold structure.
- Add soy sauce, black pepper, caraway and salt. Splash in 30ml water; this creates a quick steam burst.
- Toss for 60 seconds — the sauce should reduce to a glossy coat on the lamb. The dish is meant to be slightly wet, not bone-dry.
- Add spring onion in the last 20 seconds. Plate immediately. Serve with steamed rice or as part of a tsuivan-style platter.

Cultural Note
Mongolian mutton stir-fry — sometimes called 'Mongolian beef' in the Western tradition though the original uses mutton — is the everyday stir-fry dish. The American 'Mongolian beef' (a sweet hoisin-based dish) is unrelated to actual Mongolian cooking; the original Mongolian dish is simpler, more pepper-heavy, and uses mutton. The dish is a domestic adaptation of the broader Asian wok tradition; Mongolian cooks adopted the technique while preserving their preference for mutton over chicken or pork.
