Take one wrapper, fill the center with a small spoonful of the filling. Gently wet one half of the edges to seal. Press the edges together well. Keep dumplings covered with a clean tea towel while wrapping the remaining dumplings.
Place dumplings in a steamer basket and steam for 10-15 minutes, until wrappers are translucent. Serve with a simple dipping sauce of two parts soy sauce and one part vinegar.
