Bring a pot of water, soy, honey, garlic, ginger, turmeric, and salt to a boil. Ladle the boiling soy mixture over the skin until it looks cooked. The object is to flavor and remove the natural oils from the skin so it gets really crispy. You'll see the skin blister along the way. Then put it on a drying rack, preferably with a fan on it for an hour or three. While it's drying. Reduce the liquid until it is thickened to an oil like consistency. When the duck is dry, roast it in a covered roasting pan either in the oven or a grill. Slice it against the grain and make sure some of the crispy skin goes with each serving. Drizzle or dip in the reduction. Enjoy.
