Hákarl – Iceland

A national dish of Iceland, Hákarl is a Greenland shark that has been allowed to ferment and decay—if fresh, the shark is actually poisonous and cannot be eaten. Hákarl is known for its strong ammonia smell and fishy taste, which is why it’s recommended that beginners chase the fish down with a shot of local spirit. Icelanders are able to eat their Hákarl year-round, as the fish is sold in regular supermarkets.
