I've eaten a lot of muskrat but not the tail. I tried beaver tail once not that great.
I think muskrat tastes a lot like early season puddle ducks, just different shaped pieces. If the beef only people up here really got hungry and lived by a slough in a non-drought year when there were mrats around, they'd learn to eat them.
Isn't a person supposed to make soup out of the beaver tail? I tried frying one in college. Poor choice of cooking. It was like eating a greasy rubber biscuit. I think it ended up hanging out in our day room for a while until someone finally threw it away.
