I have always processed the game I have shot over the decades but Moose has not been one of the species.
Elk and venison are very fat free and there are only two ways of cooking unless you grind and make burgers where the addition of fat is required.
I never have sausage made as that just adds lots of fat, salt and preservatives.
My hunting buddy always had Perkins in Crivitz where I mostly hunted make a double garlic sausage which I really could not tell from most commercial brands.
For Elk/Venison tenderloin/steaks, seared rare , served piping hot is the only way for those cuts. A splash of Dale's or make your own from grated ginger and shoyu adds salt.
The other cuts require long slow moisture brazing.
There is definite taste difference between venison from Northern Wisconsin/ Upper Michigan and venison from South Eastern Wisconsin. Up North, the deer feed on browse that could contain anything they can reach standing on their hind legs.
In Kenosha county the deer prepare for the Winter on corn, soybeans. A much milder taste.
Squirrel does not taste like anything other than wild turkey legs/wings as they both eat acorns.
Squirrel is very hard to clean as the skin is very tough. Cook either like fried chicken or long and slow. For wild turkey the breast can be cooked like a domestic turkey and the leg/thigh and wings crock potted. Add sour cream at the end if desired.
Bear is another story , probably the best wild game of the non-flying species.
It must be well done but because of the high fat content, it's like Prime Roast Beef.
So there you have it in a 'nutshell' so to speak for cooking four legged species found in Wisconsin.
