Live shrimp flash-poached in boiling water with a little ginger, scallion and rice wine for under a minute—just until the shells turn red and the bodies curl. Eaten shell-on at the table, dipped in light soy with slivered ginger and scallion. The plainest of Cantonese seafood dishes, it adds nothing that masks: it lives or dies on the freshness of the shrimp.
Blanched live shrimp is the textbook case of bai zhuo, one of the core cooking methods of Cantonese cuisine. "Zhuo" means to cook raw food briefly in rapidly boiling water; "bai" (literally "plain/white") means cooking without soy sauce or coloring, so nothing tints or overwhelms the ingredient. The method has no datable inventor—it is a classic Cantonese technique of indeterminate age, rooted in the regional ethos of bun mei ("the ingredient's own flavor") and eating things only in season. Cantonese cooks reserve the "original-flavor" form of blanching especially for shrimp and tender greens, where the whole aim is to set the food just to doneness and serve it the moment it is cooked.
You peel the shell at the table, sometimes sucking the head first. The flesh underneath is firm and springy—just-set, never mushy—and tastes clean and sweetly briny, the shrimp's own flavor with nothing layered over it. A quick dip in the soy-ginger-scallion sauce lifts that sweetness rather than burying it. Done right, every bite snaps; a shrimp that is soft or cottony has been over-cooked, or wasn't fresh to begin with.
The whole method is built on doing as little as possible. Shrimp muscle is mostly water held by protein, and that protein sets fast: in a rolling boil the shell turns red and the body curls in well under a minute, and at that moment it is done. Cook it longer and the proteins over-coagulate and squeeze out moisture, so the flesh turns rubbery and woody—the same failure as any over-boiled lean meat. The shell is left on for a reason: it shields the flesh, slowing moisture loss and keeping the sweetness in, which is what gives the bouncy, snapping bite. The shells turn red because, in the live shrimp, the orange-red pigment astaxanthin is bound to a protein (crustacyanin) that masks it as a slate blue-grey; heat denatures that protein, the bond breaks, and the freed astaxanthin shows its true red. And because nothing is added to cook it, there is nowhere to hide a stale shrimp—freshness, ideally live shrimp, is the entire game.
Variations
The bai zhuo method extends well past shrimp: blanched choy sum (bai zhuo choy sum), blanched squid, and blanched sea whelk are all standard, each finished the same plain way. Many cooks shock the shrimp in ice water straight after poaching for an extra-snappy bite. The dip varies by household and region—light soy with ginger and scallion is the base, some add a little fish sauce, and others pour hot oil over the ginger and scallion to bloom their aroma. The Chaoshan kitchen likewise prizes plainly blanched seafood eaten with a simple dip.

6 steps · 10 min
- 15 min
Rinse the live shrimp clean. Trim the long feelers and sharp rostrum with scissors; leave the shells on. If you like, snip the back and pull the dark vein.
- 22 min
Bring a pot of water to a rapid rolling boil. Add a few slices of ginger, a length of scallion and a splash of rice wine.
- 31 min
Drop in the shrimp all at once. Poach 30 to 60 seconds, just until every shell has turned red and the bodies have curled.
Watch outDrop all the shrimp in at once and pull them in 30–60 seconds, the instant every shell turns red and the bodies curl — a few seconds too long and the sweet flesh turns woody.
- 41 min
Lift the shrimp out immediately. For an extra-snappy bite, plunge them into ice water for a few seconds, then drain.
Watch outPlunge them straight into ice water for a few seconds — the cold shock tightens the flesh for that signature snapping bite.
- 52 min
Make the dip: light soy sauce with finely slivered ginger and chopped scallion. Optionally heat a little oil until smoking and pour it over the ginger and scallion.
- 61 min
Pile the shrimp on a plate and serve at once with the dip alongside. Peel at the table and eat shell-off, dipping each one.
