It's really not bad... Didn't know what to expect so I just tossed it on the grill, chunked it up, and added bar-b-que sauce. Were I to do it again, I believe I'd run it in the pressure cooker a bit before throwing it on the grill. Or grill it a bit, and toss it in a slow cooker with some bar-b-que sauce and let it simmer awhile to tenderize it.
Flavor was a little gamey, but not objectionable. I've had goose that was way worse. Bar-b-que sauce covered it pretty good. Might want to marinate it, if you, or anyone you're serving isn't into gamey flavor. The chewy part was worse than flavor.
Honestly, it seemed to have some serious potential, and with a little experience cooking it, I'd say it would probably make pretty good table fare for a Sunday afternoon beer drinking ballgame watching event. I'd get everyone drunk and hungry, then whip it on them, and wait until they'd ate it all to tell them what it was.
