The art of making Chinese dumplings (jiaozi, wontons, baozi, shao mai) encompasses dough making, filling preparation, wrapping technique, and multiple cooking methods. The wrapper is a hot-water dough (for jiaozi) or a leavened dough (for baozi), and the filling follows strict principles of seasoning, binding, and juiciness. The pleating of jiaozi — 12-18 pleats per dumpling — is both functional (creates seal) and aesthetic.
For jiaozi wrappers: boiling water poured into flour creates a dough that's soft, pliable, and slightly translucent when cooked. The hot water partially gelatinises the starch, making it elastic. Rest 30 minutes. Roll into a snake, cut into pieces, roll each into a thin round — thinner at edges, slightly thicker in centre. For filling: meat must be stirred in one direction only to develop myosin binding — this creates the bouncy, juicy texture. Season with soy sauce, sesame oil, ginger, white pepper. Add stock or water gradually while stirring. Napa cabbage must be salted and squeezed dry before adding.
For soup dumplings (xiao long bao): add gelatinised pork stock (aspic) to the filling — it melts during steaming, creating the soup inside. For potstickers (guotie): fry in oil until bottoms are golden, add water, cover, steam until wrappers are translucent, uncover, let water evaporate until bottoms crisp again. That sequence — fry, steam, fry — is the technique behind the crispy lace skirt. Freeze dumplings on a tray before bagging — they'll keep their shape.
Using cold water for jiaozi dough — produces tough wrappers. Not resting the dough. Rolling wrappers to uniform thickness — the centre needs to be slightly thicker to support the filling. Stirring filling in random directions — disrupts myosin network. Filling too wet — dumplings burst during cooking. Not sealing properly — any gap and they open in the water.
