One of the delicacy of Iceland is the Hákarl
Hákarl or kæstur hákarl is a food from Iceland consisting of a Greenland shark or sleeper shark (Somniosus microcephalus) which has been cured with a particular fermentation process and hung to dry for four to five months. Hákarl is an acquired taste; it has a very particular ammonia-rich smell and fishy taste.
There's also an episode of the F Word with Gordon Ramsey and James May giving it a try.
Gordon Ramsey throws up
I don't actually think I'd have the gut to try it but I think it would really be an awesome souvenir to all my friends. So the question is: is it possible to buy it in a store and bring it back in Italy or it needs to be refrigerated? Are there any law regarding import/export of the Hákarl?
