Pekin is a joy to eat, but difficult to process. A lot of people just pull the skin off, which is a waste of the best part. If your dad and hub have the patience to pull all the pins out, good for you. It is tough trying to find a butcher to do it, and expensive (i.e., that's why the ducks in the freezer dept go for $25 or more, and they are Giant Pekins).
So easy to roast, yes, prick the skin all over, taking care not to pierce the meat. Also make sure the baby is room temp before roasting, and dried real well inside and out (makes for crisper skin). All of the suggestions here are great, it's a matter of taste. You can make your orange sauce on the side for those who like that, they can use it like gravy, just add a little duck fat drippings to it for flavor (and also a tablespoon or 2 of gran marnier or other orange liquer). Siphon off the duck fat as it roasts and put in a saucepan and on very low heat, let it "render", emphasize low heat, or it will splatter. This simply removes moisture and adds even more flavor. Let it cool and store in covered container in fridge, and use it for EVERYTHING! Like ours on rye toast, use it like butter. Saute just about anything in it, and the french fries are the best you will ever have. Duck fat is actually lower in cholesterol than butter, and some oils. Another advantage to making the orange sauce on the side is that it won't flavor the pan drippings, if you decide to baste the duck with the sauce, make sure you have gotten all the fat you can from the pan before applying and brush it on at the end of roasting.
A time consuming but really neat trick to get the crispiest skin, is to set your duck (after wiping to dry) in front of a fan on low, aimed at the insides, for a couple of hours. The drier you get the bird, the better (it almost becomes PEKING duck, but that's another story) and crisper. You should also roast your duck so it is a little pink, don't be afraid of that. Most restaurants serve it rare to medium rare, unlike chicken.
This past spring we ordered 15 pounds of rendered duck fat from a farm in PA. That's how much we love it for cooking. Put it up in pound containers and froze it, pull it out as needed. Keeps in fridge for weeks and weeks.
Sounds like there are some good duck chefs here, experiment and enjoy, you will be hooked!!! Ducklucky.
