Teriyaki shark-on-a-stick would be good start..............
Its gotta be butchered right away, as shark meat (and all other fish related to shark, like skates, rays, etc.) spoils quickly due to high concentration of urea in the meat. An unpalatable ammonia-like flavor is what you get.
Had skate with that tinge of ammonia flavor at a high end restaurant once, and the clueless chef came out to insist that this was normal. BS!
