Fresh small oysters from the Qigu lagoon on Tainan's coast, served raw on the half-shell or briefly blanched, with lemon, soy-ginger or chili. The defining seafood of Tainan's coastal oyster-farming region.
Qigu oysters are the defining seafood of the Qigu lagoon on the southwestern coast of Tainan, one of Taiwan's richest oyster-farming regions, where the brackish lagoon waters have nurtured suspended long-line oyster cultivation for generations. The Qigu oyster is small, intensely briny and sweet, prized for its clean flavour, and it is eaten as fresh as possible, either raw on the half-shell with lemon, or briefly blanched and served with soy-ginger or chili. The lagoon's oyster farms, the racks and long lines visible at low tide, are also a tourist attraction, the roadside stalls selling oysters opened to order, eaten within minutes of leaving the water. The Qigu oyster is closely related to the oysters used across Tainan's famous oyster omelettes and vermicelli, but eaten alone, fresh and uncooked, it is a different dish, a celebration of the raw ingredient. The oyster-farming tradition, and the care taken to keep the lagoon's water quality high, is the foundation of Tainan's broader oyster cookery, and the freshness of the Qigu oyster, eaten within hours of harvest, is the point.
Small, plump, intensely briny oysters on the half-shell, the meat sweet and metallic-clean, the liquor sea-salty. Eaten raw with a squeeze of lemon, or blanched for seconds and dipped in soy-ginger; the freshness the whole thing.
The dish is a showcase of freshness, the technique being the shucking and the briefest of cooking if any. Oysters are harvested from the Qigu lagoon's long lines, scrubbed clean, and opened to order with an oyster knife, the muscle cut and the meat left on the deeper half-shell with its liquor. For raw service, the half-shell oysters are presented on ice with lemon wedges, eaten within minutes of opening, the briny liquor and sweet meat the point. For the blanched version, popular in Taiwan, the shucked oysters are rinsed briefly, dropped into boiling water for 5 to 10 seconds only, just until they plump and the edges ruffle, then drained and served with a dip of soy sauce, rice vinegar, sugar and minced ginger. The blanch must be brief, over-cooked oysters shrink and turn rubbery. The oysters are sometimes breaded and fried for a different dish, but raw or blanched, they are the simplest and purest expression. The lagoon water quality, monitored by the farms, is what makes raw consumption safe.
Variations
Oysters are also fried in the famous oyster omelette. A grilled version with garlic and butter is a street snack. The oysters are bottled in their liquor for export.
