Xiaolongbao: Soup Dumplings
Xiaolongbao — the Shanghainese steamed soup dumpling containing both a filling and a liquid broth within the sealed wrapper — achieves the liquid interior through a technique of extraordinary ingenuity: the broth is made into a gelatin (aspic) that is solid at room temperature, mixed into the filling, and melts to liquid during steaming. The wrapper encases a solid filling; service reveals a liquid soup.

The Method
1
Braise the pork skin (or pig's foot and whole chicken) in water until the collagen has fully rendered. Strain the stock, discard solids, and reduce over moderate heat to concentrate. Pour into a shallow tray and refrigerate until completely firm. The aspic is ready when it holds a clean-cut edge and does not yield to fingertip pressure.
2
Cut the chilled aspic into dice of 4–5 mm. Combine with the minced pork filling and mix until evenly distributed. Keep refrigerated until the moment of wrapping; the aspic must remain solid throughout assembly.
3
Add boiling water gradually to the all-purpose flour and work to a smooth, pliable dough. Rest, covered, until the dough relaxes and rolls without resistance. Roll portions into wrappers thin enough that the filling is faintly visible through the dough, yet with sufficient strength to hold during steaming.
4
Place a portion of filling at the centre of each wrapper. Gather the edge and pleat, working around the circumference to achieve 18 pleats, each folded and pressed firmly against the next, gathered and sealed at the crown. This is the step on which the dish lives or dies: a pleat that opens during steaming will release the broth and the dumpling is lost.
5
Arrange the sealed dumplings in a bamboo steamer lined to prevent sticking. Steam over vigorously boiling water for 8 minutes. The dumplings are ready when the wrappers turn translucent and the filling is fully set; the aspic will have melted completely to liquid broth within.

Quality Hierarchy
01
Reserve — Stock drawn from a full braise of pig's foot and whole chicken together, reduced to a dense, trembling aspic of exceptional clarity; wrappers rolled by hand to the exact translucency that reveals the filling beneath.
02
Estate — Pork-skin aspic, well reduced and very firm; hand-rolled wrappers with a consistent 18-pleat fold; filling kept cold throughout assembly.
03
Market — A gelatinous pork stock set to a workable aspic, cut to the specified 4–5 mm dice; wrappers rolled thin with pleat count approaching the benchmark.
04
House — Any firmly set pork-based aspic diced into the filling and enclosed in a thin hot-water dough wrapper, steamed 8 minutes — the essential liquid-interior effect preserved even if pleat count is lower.

Sensory Tests
◇Touch. The chilled aspic holds a clean-cut edge and does not yield when pressed — it is firm enough to dice without smearing.
◇Touch. The rested dough rolls smoothly without springing back and feels supple but not sticky.
◇Sight. The rolled wrapper is thin enough for the filling to show faintly through the dough.
◇Touch. Each pleat, pressed between thumb and forefinger, stays closed and does not spring open — the seal is secure.
◇Sight. After 8 minutes of steaming, the wrapper has turned translucent and the filling is fully set within.
◇Where it lives or dies. The pleat seal at the crown of each dumpling must be airtight — any fold that opens during steaming releases the broth and the dumpling cannot be recovered.

What to Pour
A light, off-dry Riesling or a clean Shaoxing rice wine served at room temperature; the gentle residual sweetness and acidity cut the richness of the pork without overwhelming the delicate broth.
