Mix the soy sauce, wine, sugar and ginger in a bowl.
Arrange the wings in a foil roasting pan in one layer. Pour the sauce over the wings and put the wings in the oven.
Set the oven to 400 °F (204 °C) and cook the wings for 30 minutes. Turn the wings and cook them for another hour. Poke the largest one with an instant-read thermometer. They are done at 165 °F (74 °C).
Transfer the wings to a platter. Impress your guests and sprinkle gold flakes on the wings. Be sure to provide a bowl for bones and plenty of napkins for wiping fingers.
