Cantonese Lobster Preparation (Long Xia)

Cantonese lobster preparations: live lobster dispatched and prepared in multiple styles — ginger-scallion stir-fry (jiang cong chao long xia), steamed with garlic and vermicelli (suan rong fen si zheng long xia), lobster congee from the shells (long xia zhou). The ginger-scallion wok preparation is the Cantonese standard — the lobster cut live into pieces and stir-fried at maximum heat.

The Method

1
Dispatch the lobster humanely on the board immediately before cooking — never use a lobster that has been distressed or left to die. Separate the head from the tail. Reserve the coral and tomalley from the head cavity; do not discard them. Split the claws with a heavy cleaver so they will cook at the same rate as the tail pieces. Cut the tail through the shell into sections of approximately 4 cm. Dust all cut surfaces lightly with cornstarch. The pieces are ready when every cut face carries a fine, even powder with no bare wet patches.
2
Heat the wok over the highest available flame until a drop of water vaporises on contact. Add the oil and swirl to coat. The wok is ready when the first wisps of smoke rise from the surface — any lower temperature and the lobster will steam rather than sear, and this is where the dish lives or dies. Lay the lobster pieces cut-side down in a single layer and sear without moving for 90 seconds. Turn and sear the shell side for a further 60 seconds. The cut surfaces should show a faintly golden, lightly crisped crust.

3
Pour in the Shaoxing wine — it will flash and steam. Add the soy sauce and the reserved coral and tomalley; stir these into the pan juices so they emulsify into the sauce. Total wok time for the lobster pieces must not exceed 3 to 4 minutes from first entry; remove the pieces to a warm plate the moment the shells are vivid red throughout and the exposed flesh is just opaque.
4
Off the heat, add the ginger and spring onion to the residual heat of the wok. Toss for no more than 20 seconds — they must remain bright green and fragrant, not wilted or browned. Finish with sesame oil, season with salt, and return the lobster pieces to coat. The aromatics are correct when they release a clean, sharp fragrance without any scorched note.

Quality Hierarchy

01
Reserve — Live native lobster, dispatched on the board seconds before cutting; coral and tomalley fully intact; cooked in a seasoned carbon-steel wok over a professional gas range capable of true maximum flame.
02
Estate — Live lobster from a reputable fishmonger, dispatched at home with confidence; domestic gas burner pushed to its highest setting with the wok preheated for a full two minutes.
03
Market — Live lobster of moderate size; domestic wok over the largest gas ring; results leaning toward a light steam-sear rather than a full sear, but the aromatics remain correct.
04
House — Lobster tails only (fresh, not frozen); cornstarch dusting and maximum domestic heat still produce a respectable dish, though the depth given by coral, tomalley, and shell is absent.

Sensory Tests

◇Sight. Every cut surface carries a fine, even dusting of cornstarch with no bare wet patches before wok entry.
◇Sound. The lobster pieces crackle and spit loudly on contact with the wok — a subdued sizzle signals insufficient heat.
◇Sight. Shells are vivid uniform red throughout and exposed flesh is just opaque — not translucent, not shrunken — at 3 to 4 minutes total.
◇Smell. Ginger and spring onion release a sharp, clean fragrance with no scorched or sulphurous note when tossed off the heat.
◇Where it lives or dies. The wok must be at maximum heat before the lobster enters — at any lower temperature the pieces steam in their own moisture rather than sear, and the defining wok-breath (wok hei) of the Cantonese preparation is lost entirely.
