and has a strong smell, similar to that of many cleaning products. It is often served in tiny cubes on toothpicks. Those new to it may gag involuntarily at 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 odor is much stronger than the taste. It is often eaten with a shot of the local spirit, a type of akvavit called

The meat of the Greenland shark is poisonous when fresh because of its high

and trimethylamine oxide content. However, when properly processed, it may be consumed safely. The traditional method begins with gutting and beheading a shark and placing it in a shallow hole dug in gravelly sand, with the cleaned cavity resting on a small mound of sand. The shark is then covered with sand and

, and stones are placed on top of the sand in order to press the fluids out of the body. The shark ferments in this fashion for six to twelve weeks, depending on the season. Following this curing period, the shark is cut into strips and hung to dry for several months. During this drying period, a brown crust will develop, which is removed prior to cutting the shark into small pieces and serving. The traditional preparation process may be observed at Bjarnarhöfn Shark Museum on Snæfellsnes. The modern method is simply to press the shark's meat in a large plastic container, into which drain holes have been cut.
