Hakarl, which is an Icelandic delicacy, is a dish that's served during the Icelandic midwinter festival, Thorrablot. Usually taken with a shot of "brennivin" (a strong spirit made from potatoes), this unique dish has been described by some to have a powerful "cheesy" flavor, while others have described it as the vilest thing they ever tasted, almost akin to solid urine. But it's not the unique taste of this delicacy that puts it on the map, but rather what it actually is--rotten shark meat.
