Using a fork, pierce the duck skin all over to allow the flavor of the marinade to penetrate and the fat to drain. Combine honey, soy sauce, coffee, ginger, miso and brown sugar together in a bowl, stir well to dissolve the brown sugar and miso. Squeeze the citrus juice into the marinade then stuff the cavity of the duck with the citrus halves. Place the duck in a 2 gallon freezer bag, then pour in the marinade. Seal and refrigerate for 24 hours.
The next day, remove the duck from the marinade and pat it dry with paper towel. Preheat oven to 450 degrees F.
Place the duck on a rack in a roasting pan. Fold the wing tips back and tie the legs together. First, roast the duck for 20 minutes, the high temperature will caramelize the sugars on the outside of the duck and set a rich mahogany color. After 20 minutes, drop the temperature down to 325 degrees F and roast for 1 hour. Duck heaven baby!
You can start the bok choy when the duck has about 10 minutes left in cooking. Preheat a large skillet on medium high. Add peanut oil.
Saute cut side down for about 1 minute until golden. Discard the oil. Take the back-side of a knife and give the ginger a good whack. Bruising the ginger will release a ton of flavor. Add the ginger to the pan with bok choy then add the mirin, soy, and chicken stock. Stir in the miso, careful not to damage the food.
While you have the spoon in your hand, stir in the cornstarch mixture, then let the sauce simmer and thicken for a few minutes. Finish with the fresh cherries, a pinch of salt, and fresh cracked white pepper.
