If the fish is longer than the pan, make a ball of foil to support the fish’s head. Cut three or four diagonal slits in the fish. Put two or three pieces of green onions in the slits. Pour one cup of the Asian marinade over the flounder. Refrigerate for one hour. Preheat oven to 425°F. Mix together the five-spice powder with the brown sugar and press the mixture into the fish. Roast the fish for 20 minutes, then broil it for five minutes on high. The fish should be firm, and its flesh should flake around the edges.
