Siu Mai
Open-topped steamed dumplings of pork and shrimp wrapped in yellow wheat-egg wrappers, garnished with a dot of crab roe or carrot — Cantonese dim sum's standard partner to har gow.
Yellow wrapper, open top.
Cantonese siu mai uses a thin, square, alkaline egg-and-wheat wrapper — the same kind used for wonton skins. The wrapper is gathered loosely around the filling but the top is left open, exposing the meat. A single dot of orange-red crab roe (*haam zin*) or shredded carrot is placed on top as a visual marker. The dish belongs at the top of the dim sum cart, beside har gow, as the canonical pair.

Siu Mai
Open-topped steamed dumplings of pork and shrimp wrapped in yellow wheat-egg wrappers, garnished with a dot of crab roe or carrot — Cantonese dim sum's standard partner to har gow.
A dish whose history runs from inner Mongolia to Hong Kong. Northern Chinese shao mai — larger, sticky-rice-filled, wrapped in a thicker wheat skin — was already being served in Hohhot tea houses in the late 14th century. The dish travelled south along trade and migration routes, and by the time it reached Guangzhou it had been reshaped: pork-and-shrimp filling, thinner yellow wrapper, open top, single dot of decoration. The Cantonese version dominated dim sum from the 19th century onward and is the one most-exported.
The dish carries a quiet status anchor in the Cantonese yum cha tradition. A skilled dim sum chef makes siu mai’s filling juicy without being watery, well-seasoned without being salty, and visually plump enough that the wrapper looks tight. The classic siu mai test for a new dim sum kitchen is whether the dumpling reads as eight bites or three. Three is right; eight means the kitchen has been timid.
Eaten before the cart cools.
Siu mai is best within minutes of steaming. The fat in the pork mixture should still be soft and shiny; the dumpling should yield to chopsticks with the kind of give that says the wrapper is sticky from steam. A siu mai that's been sitting under a heat lamp for half an hour reads chewy and dense; the dim sum tradition is built around speed of service, and old siu mai is its own kind of failure.
