Wanning mud crab steamed plain with ginger and scallion, prized for the deep-orange roe from Hele harbor's plankton-rich brackish lagoons.
One of Hainan's 'Four Famous Dishes' since the Qing dynasty, alongside Wenchang chicken, Jiaji duck, and Dongshan goat. Hele (和乐) is a fishing harbor in Wanning on Hainan's east coast, where the Taiyang River meets the South China Sea through a chain of brackish lagoons. The plankton density there is unusually high; mud crabs grown in those waters develop denser, deeper-pigmented roe than the same species farmed inland.
One of Hainan's Four Famous Dishes since the Qing dynasty. Hele is a fishing harbor in Wanning where the Taiyang River meets the South China Sea — plankton-rich brackish lagoons load Scylla paramamosain with carotenoids that inland-farmed crabs of the same species can't develop. Belly-up steaming holds the roe in place.
Crack the shell and what spills out is the whole point — a thick layer of deep-orange roe, almost custardy, set just enough to scoop. Meat is sweeter and softer than northern hairy crab, less brassy. Dip the roe in ginger-vinegar; it cuts the richness without overwhelming. The leg meat is mostly an afterthought here. If the roe is pale yellow and runny, the crab wasn't from Hele or wasn't in season.
Roe color and density are diet-driven: Hele's lagoons have year-round plankton blooms rich in carotenoids, which the crab deposits in its hepatopancreas as orange-red pigments. Inland-farmed crabs of the same species (Scylla paramamosain) develop pale yellow, less dense roe. The belly-up steaming position matters too — gravity holds the liquid roe in the cavity instead of dripping out, so it sets into a single block.
Variations
Hele banquet standard belly-up steamed with ginger-vinegar; Wanning pier shops crack and stir-fry with garlic; Sanya tourist versions chili-fry the same crab and bury the roe under sauce — locals consider that wasteful.

Ingredients
Serves 2How it's made
5 steps · 10 min active + 15 min waiting
- 115 min
Buy live female mud crabs from Hele harbor (or live mud crabs, 500g each). Chill in ice water for 15 minutes to slow them — easier to handle and the flesh contracts less when steamed.
- 23 min
Brush the shells under cold water. Tie each crab with kitchen twine — claws to body — so the legs don't drop off during steaming.
- 31 min
Lay 4 thick ginger slices and a knot of scallion in a steamer plate. Place crabs belly-up — keeps the roe from leaking out the apron.
Watch outSet the crabs belly-up in the steamer — that way gravity keeps the runny roe pooled in the shell so it sets as one block.

Steam over rolling water at full heat for 12 minutes per 500g crab. The shell turns deep orange-red. Don't open the lid early — temperature drop seizes the meat.
Watch outSteam hard over rolling water and don't lift the lid early — a temperature drop seizes the meat tough; shell goes deep orange-red when done.

Mix the dip while the crabs steam: 3 tbsp Hainan red rice vinegar, 1 tbsp grated ginger, 1 tsp sugar, pinch of salt. Serve crabs whole with the dip in small bowls.
