The only time I Would eat a possum if I was starving to death. I have heard all the stories about Grannies great possum and gravey or with dumplings . Think I Would eat rat first. The one time I tasted spit in out nasty taste.
The blubber isn't what you were chewing... it was the black part... the skin. The key to eating it is, to cut it really thin after cutting it into chunks. Easier to manage that way.
