Sorry that my duck and goose recipes are all conventional.
Such cooking methods are limited is scope, prepare, season, baste heat/cook. About the only room for any flexibility is in the varieties of seasoning. All of the rest is same, same.
Here are some links.
https://www.google.com/search?sourc...2i30.0.0.1.96094...........0.y4FfxXOz8J8The U Tube video's of cooking a Wild Goose are pretty good. I like one of them - roasting. Simple and basic. Lots of basting with lemon juice, cognac and bourbon. Sea salt. Garlic. Breasts removed, carcass, thighs, legs in the oven 40 minutes at 350 degrees, then add in the breasts to not overcook them.
And on the BBQ. Lots of brining and seasoning. Seven different types. That recipe is similar to the one I read in American Rifleman. Those spices and condiments will cost $4 to $5 each around my parts thus $28 to $35. Traditionally I usually only utilize a small portion of a bottle and the rest sits in my cabinet for years and eventually gets tossed.
About the only geese I have access to are the Canadian honkers. Pretty much gave up on those. Neither I nor family ever developed a taste.
There is quite a spread in varieties of ducks. Some of those that feed heavily on fish are so strong that they are almost unpalatable. Note that domestic duck is one of my favorites however.
Only other thing I can suggest is Eileen's sausage recipes. 50% goose/duck/50% pork shoulder with fat.
I suppose it is pride that drives a hunter to want to eat his game, and rarity. You just can't buy that stuff in any restaurant other than some that specialize in farm raised wild game that is not under the State game laws.
