Of all the wild meat (vermin included), possum has to be the worst. It smells like rotted pork while going thru the requisite 3 changes of water after cutting off all the fat.
I was once married to an indiscriminate hunter, who brought everything home. I have attended a private wild game dinner hosted by a chef. Some interesting dishes and some just too heavily spiced/sauced to judge. A few miles from here, a group of hunters ended their annual game dinner after a cluster of cases of prion disease. I believe one contributor was squirrel brain in the burgoo.
Raccoon, OTOH, can be made edible. Squirrel is a matter of taste, I guess. Pretty tough and needs to be pressure cooked.
Venison is wonderful, of course. Rabbit is good, as well.
Roadkill? EWWWWWWWW!
BTW, Aussie *possum* is not the same as American o’possum.
An elderly man I worked with told me once that during the Great Depression his family and a lot of others ate groundhogs and he said they are great. They don’t scavenge and they are grass and plant eaters. One thing about it....we will never starve around here. We have groundhogs everywhere. LOL
