Lutefisk (literally “lye” fish) is a seafood dish and traditionally a part of the Christmas feast in several Nordic countries. It is made from aged stockfish (air-dried whitefish), or dried and salted cod, cured in lye. It is gelatinous in texture after being rehydrated for days prior to eating.

Lutefisk is traditionally served with boiled potatoes, mashed green peas, melted butter and small pieces of fried bacon and/or white sauce but there are several  regional variations.
