I would try the noses of caribou and perhaps even the tail of a beaver. Gizzards on the other hand are a well-respected part of classic French cuisine. "Salade au gesiers" is a staple, and very tasty too.
I've had good scrapple, and hush puppies, and giblets are usually packaged in turkeys, often finding their way into dressing (stuffing) at Thanksgiving. Jay, see all you've missed!!
