How to Pleat a Dumpling: Gyoza Half-Moons, Momo Gathers, and More

Pleating looks like pure decoration, and part of it is — a row of neat, even pleats is one of the most recognisable signs of a well-made dumpling. But pleats also do real structural work: they gather up the extra dough created by folding a flat circle, letting the seam close tightly without a lump of excess dough bunching in one spot.

Why folding a circle in half creates extra dough to deal with

Fold a flat circle of dough in half and the two straight edges meet perfectly along the fold, but the curved edge doesn't — there's more material along that arc than a flat seam needs to close cleanly. Pleating takes up that slack in small folds along the curve rather than leaving it as loose, floppy dough. That's the entire mechanical reason pleats exist on a half-moon-folded dumpling like a gyoza.

The gyoza half-moon pleat

Hold the filled, half-folded wrapper in one hand with the curved seam facing you. Starting from one end, pinch a small fold of the top layer of dough toward the middle, pressing it against the flat bottom layer to seal. Repeat down the length of the seam — five to seven pleats is typical for a standard-sized wrapper. The bottom layer stays flat, which is exactly what you want, since that flat side is what sits in the pan for the crisp sear in a classic potsticker.

The momo spiral gather

Momo isn't folded flat at all — the filling sits in the center of a round wrapper, and the dough is gathered upward around it from every direction, twisted into a small pouch at the top. Because the whole circumference needs gathering rather than just a folded curve, momo takes many more small pleats than a gyoza — often close to twenty on a similarly sized wrapper. The technique is closer to gathering a drawstring bag than folding a taco.

The empanada repulgue

Empanada's traditional edge, the repulgue, is a rope-like twist rather than a series of small pinches: fold the dough over the filling into a half-moon, then, working from one corner, fold a small triangle of the edge over itself and press down, repeating along the seam so each fold overlaps the last. The result looks more like a twisted rope than a pleated fan, and because empanada dough is thicker and often fried or baked, this sturdier seal matters more than it would on a thin steamed wrapper.

The pierogi crimp

Pierogi usually skip individual pleats altogether in favor of a firm crimp: press the folded edge closed with your fingers or the tines of a fork, working along the seam in overlapping presses rather than distinct pinches. Because pierogi dough is enriched and a bit more elastic than a plain wheat-and-water dough, it seals well under simple pressure without needing pleats to manage excess material the way a thin gyoza wrapper does.

Getting an even result

Consistency comes from a consistent starting point more than from folding speed: use the same wrapper diameter and the same portion of filling every time, and mark a mental (or literal) center point on the wrapper before you start folding so your pleats stay evenly spaced. If a batch is coming out uneven, it's very often because the filling amount is drifting piece to piece — go back and check with a scale before assuming the folding technique itself is the problem.

Pleating is also one of the few kitchen skills that genuinely improves with pure repetition. The first dozen or so from any new dough or fold style are usually the roughest-looking of a session; by the second or third dozen most home cooks find a rhythm that produces noticeably more even results.
