I've had canned seal meat from an uncle in Newfoundland. It was not bad, tasted kind of like fishy roast beef.
The meat is far better. Still not what I would call "good", but much more tolerable. The oil is like concentrated bilge water from the fish hold of a trawler. Except also greasy and thick. Open an eye dropper of that shit in a room and you'll puke for the rest of your life.
