corn on the cob stickers and pierce the skin all over very lightly.
Salt that baby down.
Do the corn sticker thing a couple more times while it cooks, to render the fat out.
Save the fat for fries.
Cut out the breast, leg and thigh like any other bird and serve.
Save the carcass to make duck stock for gumbo.
If you want glaze it with something right before it is done or have it on the side as a dipping sauce so you don't pollute your duck fat.
