Do this
Wet the far half of the wrapper edge. Fold it over the filling. Pinch small folds on the front side only, working left to right.
Why it works
Folds on one side make the dumpling curve. The back stays flat and sits well in the pan. The tight seal keeps juice inside.
When to skip it
Skip the pleats for boiled or soup dumplings. A simple half-moon seal is enough there.
