Pluck out all visible feathers.
Bring to boil a big pot of water. Dip the duck in and remove after 30 seconds. Do this 4 times.
Hang the duck by its neck in a place with draught. I just use a fan to blow at the duck, until the skin of the duck is dry and 'plasticky'. It took me 2 hours.
Meanwhile, make the pancake (see below).
Brush the duck with the coating sauce. Do this 5 times, with a little time in between for the sauce to be absorbed.
Hang the duck to dry or put it uncovered in the fridge for another two hours.
Preheat the oven to 230C.
Put the duck in a roasting pan, breast side up and cook for 8 minutes.
Turn the duck over using a towel (never never a tong or fork!) and roast for 8 minutes.
Lower the heat to 180C, and roast breastside up for another 20 minutes.
Lower the heat to 120C, roast for another 10 minutes.
Turn the duck belly down/ Crank it up to 180C again for 10 minutes. Watch careful this time, as the duck will burn easily now.
Rest the duck for 20 minutes before carving.
