The canonical Northern Chinese dumpling: pork and napa cabbage filling in a hot-water dough wrapper. This is a family-scale batch — make 40–50 dumplings in one session. They freeze well; cook from frozen with an extra 2 minutes in the boiling water.
Before you start
Read the steps once through. The sequence matters: salt the cabbage first (step 1), then make the filling (steps 2–3), then the dough (step 4), rest the dough (step 5), then assemble. The resting time is built into the workflow — you prep the filling while the dough rests.
The dough
Hot-water dough (烫面) is the correct dough for jiaozi. Cold-water dough produces a chewier, more elastic wrapper that is harder to roll thin and snaps back when pleated. The hot water partially cooks the starch, reducing elasticity and making the wrapper pliable. The wrapper should stretch easily around the filling without springing back.
The 300 g / 150 ml ratio (2:1 by weight) is reliable. Humidity and flour absorption vary slightly — if the dough feels too stiff after resting, wet your hands slightly while kneading; if it sticks, dust lightly.
Squeezing the cabbage
The single most common failure mode in home jiaozi is soggy, burst wrappers caused by excess water in the filling. Squeeze the salted cabbage three times harder than you think you need to. If it is not squeezed enough, it will release water into the filling as it sits, making the mixture loose and difficult to work with, and the wrappers will steam from the inside and tear during cooking.
The filling consistency check
Before pleating all 50 dumplings, fry a teaspoon of filling in a dry pan. Taste it. Adjust seasoning before committing to the batch. The filling should taste assertively seasoned — roughly 20–30% saltier than you want the final dumpling to taste, because the wrapper dilutes it.
The three-boil method (三滚)
Adding cold water to calm the boil twice sounds counter-intuitive, but it ensures even cooking. A hard rolling boil tosses the dumplings around and risks tearing the wrappers; the cold water pauses the boil and allows heat to penetrate the filling evenly before the next stage. The third return to boil is the signal the filling is cooked through — not just the wrapper.
Freezing
Freeze in a single layer on a floured tray for 2 hours, then transfer to bags. Cook from frozen: same method, add 2 minutes cooking time. Do not defrost first.
Yield and scaling
300 g flour makes roughly 40–50 wrappers depending on how thinly you roll them. 400 g filling is right for this dough quantity. Scale up proportionally. A batch of 100 is the sweet spot for a group of four — and makes freezing worthwhile.
