Oyster-and-pork fritters from Quanzhou's Quangang district: sweet-potato-starch batter poured into plum-blossom tin moulds, loaded with fresh oysters and pork strips, then fried until the cake puffs, detaches from the mould and floats — a two-century-old salt-worker snack whose name doubles as a homophone for 'floating fortune'.
Floating cakes have been fried in the salt-farm villages of Huibei — now Quangang — for nearly two centuries, sustained by the district's abundant oyster beds and its labour force of salt workers who needed portable, calorie-dense food for long shifts. Local records name Zhuang Shishui of Shangyao village as opening the first dedicated floating-cake shop in 1888, establishing the craft as a commercial speciality. The dish is also called 福粿 (fortune cake) because 浮 is a near-homophone of 福 in the local Minnan dialect. In May 2016, 'Quanzhou snack making skills — Quangang Floating Cake' was inscribed in the fifth batch of Quanzhou City-level Intangible Cultural Heritage.
A snap of golden crust gives way to a soft, slightly glutinous interior. The oysters are briny and yielding; the pork is lightly savoury; caramelised pumpkin threads add a faint sweetness. The shatteringly crisp shell against the molten filling is the whole pleasure.
Sweet potato starch gelatinises at 60–70°C, lower than wheat starch. When the batter contacts oil at 170–180°C, the outer layer sets almost instantly into a rigid shell, trapping steam generated by the oysters' high water content inside. The enclosed steam raises internal pressure, causing the fritter to inflate, detach from the mould and float — the physics that names the dish. Pumpkin's natural sugars caramelise above 160°C, adding a brown, sweet note to the shell. Oysters are rich in taurine, glycogen and glutamate, amplifying the savoury depth of the filling.
Variations
Some shops fold fresh chives or pickled mustard greens into the batter; a purist coastal version uses only oysters without pork. Inland areas substitute minced pork for oysters where fresh shellfish are unavailable. Dipping sauces range from chilli-garlic paste to sweet soy sauce.

How it's made
7 steps · 20 min
- 110 min
Whisk sweet potato starch, water, salt and a pinch of sugar until smooth and lump-free; fold in pumpkin strips and shredded cabbage to form a thick but pourable batter
- 25 min
Rinse fresh oysters and drain well on paper towels; slice pork loin into thin strips; season pork lightly with salt and white pepper
- 35 min
Pour neutral oil into a wok or deep saucepan to a depth of 5 cm; heat to 170–180°C — a wooden chopstick tip inserted should produce steady small bubbles
Watch outCheck the oil before the mould goes in: a dry chopstick tip should raise a steady curtain of fine bubbles — too cool and the shell won't set fast enough to trap steam and float.
- 43 min
Ladle a thin base layer of batter into the plum-blossom tin mould; place 2–3 oysters and a few pork strips in the centre, keeping them away from the edges
- 52 min
Cover filling with a second thin layer of batter and press gently to seal; the mould should be nearly full
- 64 min
Lower the filled mould into the hot oil; fry for 3–4 minutes until the batter solidifies, turns golden and the fritter detaches from the mould and floats to the surface; flip once for even colour
Watch outWatch for the fritter to firm up, gild and pop loose from the mould on its own and bob to the surface — that float is the doneness tell; force it out early and the shell is still raw and doughy.
- 72 min
Fry 1 more minute until both sides are golden; lift out and drain on a rack; serve immediately with chilli-garlic sauce or rice vinegar
