Folding and pleating is the hand-shaping technique that seals a dumpling wrapper around its filling. The pleats are not merely decorative — they create structural integrity, distributing stress so the wrapper does not burst during cooking, and they orient the dumpling to sit flat during pan-frying.
The standard crescent pleat (Northern Chinese jiaozi style)
This is the most common fold and the starting point to learn.
-
Set up: Hold a wrapper flat on the palm of your non-dominant hand. Place a heaped teaspoon of filling (12–14 g) in the centre, leaving a clean border of at least 1 cm all around.
-
First fold: Bring the far edge of the wrapper up and over the filling to meet the near edge, creating a half-moon shape. Do not seal yet — just hold the two edges together at the top centre point.
-
Pleating: Starting from the right side of the centre point, use the thumb and index finger of your right hand to fold a small pleat (about 4–5 mm) in the front edge of the wrapper, pressing it firmly against the flat back. Work left, making 6–10 more pleats. Each pleat faces the same direction (right-to-left). The left corner seals flat without pleats.
-
Seal: Press the entire seam firmly between your thumb and fingers to ensure no air pockets. A properly sealed dumpling holds its shape when gently squeezed.
-
Stand: The finished dumpling should sit upright on a flat base with the pleated seam on top forming a slight curve. This flat base is critical for pan-frying (guo tie).
Simpler folds for beginners
The half-moon press: Fold in half and press the straight edge together firmly, then pinch around the curve. No pleats. This is the fastest method and works well for pan-fried dumplings where appearance is secondary.
The four-corner fold: Used for Chinese wontons (云吞). Fold diagonally to a triangle, then bring the two base corners together and press. The four-cornered shape is unsuitable for standing upright but ideal for soup — the corners catch broth.
Japanese gyoza vs Chinese jiaozi fold
The gyoza fold uses a single-sided pleat on the front wrapper only, pressed against a completely flat back wrapper. The pleating is typically more even and tighter than the Northern Chinese style, with 8–12 pleats on one side. The resulting shape has a more pronounced crescent and a completely flat base — optimal for the pan-fry-then-steam method.
Chinese jiaozi are often pleated on both sides meeting at the centre, or pleated from one side only (regional variation). Dongbei-style jiaozi tend to be larger with fewer, bolder pleats.
Wrapper thickness and rollability
The centre of the wrapper should be slightly thicker (~2 mm) than the edge (~1 mm). This counterintuitive instruction has a mechanical reason: the centre bears the weight of the filling during handling; thin centre → burst bottom. The thin edges fold and press together cleanly without creating a thick, doughy seam.
When rolling: use a small Chinese rolling pin (no handles), placing it slightly off-centre and rolling outward, rotating the wrapper a quarter turn between each roll. This naturally produces a thinner edge and thicker centre without thinking about it.
Speed and workflow
Experienced Chinese home cooks pleat a dumpling in 8–10 seconds. Beginners take 30–60 seconds. Speed matters because the wrapper dries out as it sits — dried edges do not seal cleanly and split during boiling. Keep unrolled wrappers under a damp cloth. Work in a production line if possible: one person rolling, one person filling and folding.
