Paul kirk,in his latest book,says to marinate overnight in a typical Chinese marinade of soy sauce,sugar,fresh ginger and minced garlic.
Cook at 250� for 2 to 3 hours.
If you like rare cook half as long.
This is not his whole recipe,as he is doing a stuffed duck,but may work for what you need.
We also had some recent posts on tea smoked duck,if you try the search feature at the top.
Aces Up cooking team was gracious enough to share their technique.
Place in house oven at 450�-500� for 30 mins. to flash render the fat.Better place a pan under it.
Chill overnight,so it will take up smoke.
Cook at 250� for 3 to 4 hrs.,or until the internal is about 180�.
I have not tried any of these,but maybe they will help till one of our experts logs in.
