Hákarl

Kæstur hákarl (Icelandic pronunciation: ​[ˈhauːkʰardl̥]) (Icelandic for "fermented shark") is a national dish of Iceland consisting of a Greenland shark (Somniosus microcephalus) or other sleeper shark which has been cured with a particular fermentation process and hung to dry for four to five months. Kæstur hákarl has a strong ammonia-rich smell and fishy taste.

Kæstur hákarl is readily available in Icelandic stores and is eaten year-round, but is also served as part of a þorramatur, a selection of traditional Icelandic food served at þorrablót in midwinter.

Kæstur hákarl contains a large amount of ammonia and has a strong smell, similar to many cleaning products. It is often served in cubes on toothpicks. Those new to it may gag involuntarily on the first attempt to eat it because of the high ammonia content. First-timers are sometimes advised to pinch their nose while taking the first bite, as the smell is much stronger than the taste. It is often eaten with a shot of the local spirit, a type of akvavit called brennivín.

It comes in two varieties; chewy and reddish glerhákarl (lit. "glassy shark") from the belly, and white and soft skyrhákarl (lit. "skyr shark") from the body.

The meat of the Greenland shark is poisonous when fresh, due to a high content of urea and trimethylamine oxide, but may be consumed after being processed.
