Hákarl

Hákarl or kæstur hákarl (Icelandic pronunciation: [ˈhauːkʰadl̥]) (Icelandic for "shark") is a food from Iceland consisting of a Greenland- 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 often referred to as an acquired taste and has a very particular ammonia-rich smell and fishy taste, similar to very strong cheese slathered in ammonia.
