To make the dumplings, wet the edge of a dumpling wrapper. Place a teaspoonful of the filling in the middle of the wrapper. Fold the wrapper in half to form a semicircle. Pinch the sides of the wrapper to seal the mixture. Crimp the seal with your fingers to form pleats, or use a fork. Stand the dumpling, seam side up, on a tray lined with baking paper. Repeat with the remaining filling and wrappers, keeping the dumplings separate on the tray to avoid them sticking together.
