Harðfiskur is a traditional Icelandic snack made from dried fish, typically cod or haddock. The fish is cleaned, salted, and then air-dried, resulting in a chewy texture and concentrated flavor. It is often enjoyed as a protein-rich snack and can be eaten plain or with butter. This delicacy has been a part of Icelandic culture for centuries, providing a sustainable way to preserve fish. Harðfiskur is commonly found in local markets and is popular among both locals and tourists. It is often paired with flatkaka, a type of Icelandic flatbread, for a more filling meal.
