Don,
I like a plucked roast duck a lot but if you want simple, breast the bird and leave the skin on.
In an iron skillet start the heat on low.
Slice just thru the skin with a sharp knife in a cross hatch pattern about 1\2 inch apart. Start skin side down in the pan to render the duck fat into the pan. If the duck is very lean add a bit of butter to the pan. As the fat is liquified add a bit of heat and start to turn the breast over to brown the meat on both sides. Add a bit of salt and pepper.
This goes on till the breast is just med rare. Your first few times you can cut them open to check, but after a bit you can tell by pressing on the meat with your thumb or a spoon.
Pull the breast out and set aside. Deglaze the pan with a bit of red wine. I like to add a shot of red currant jelly to this and reduce just a bit for a sauce.
Slice the breast thin and serve beside wild rice with the sauce over the meat.
Best with Mallards, Blacks, Cans, B Bill, Teal and Woodies. But I do GE and Buffies also.
Mergs, ect.. need a diff. approach. John Burbon gave me his trick which is a soak in Pineapple juice with changes in the merinade. The Pineapple is very acidic and it pulls the game flavor out.
