Soup Dumplings
Also: Xiaolongbao, XLB, Tang bao, Guantangbao, Soup buns
Thin-skinned steamed Chinese dumplings filled with seasoned pork and a pocket of liquid soup, created by enclosing meat aspic that melts during steaming.
Identity criteria
- 1Liquid soup inside the dumpling, produced by enclosing solidified meat aspic that melts when steamed
- 2A thin, pleated wheat-flour wrapper twisted shut at the top
- 3Pork-based filling (sometimes with crab) seasoned with ginger and Shaoxing wine
- 4Steamed, traditionally in a small bamboo basket (xiaolong)
- 5Eaten carefully from a spoon so the soup is not lost

Technique
- Setting and folding in meat aspic
- Solid jelly can be wrapped; on steaming it liquefies into the signature soup
- Hand-pleating a thin wrapper
- The fine pleats seal the soup in and are the visual hallmark; too thick a skin ruins the eating
- Quick steaming
- Cooks the pork and melts the aspic without bursting the delicate skin

Pork → Crab and porkadmissible
Classic premium variation
Meat aspic → No aspic (dry filling)inadmissible
Breaks the dish — without the soup pocket it is an ordinary steamed dumpling
Thin pleated wrapper → Thick bun doughinadmissible
Breaks the dish — thick dough makes a baozi, not a soup dumpling
Common mistakes
- Forgetting the aspic, leaving the dumpling soupless
- Rolling the wrapper too thick so it tastes doughy and bursts unevenly
- Over-steaming so the skin breaks and the soup leaks out
- Treating it like a baozi with a fluffy leavened bun instead of a thin pleated skin
