Caviar (less often, caviare), (from Persian: خاویار, xâvyâr "egg-bearing"), is a delicacy consisting of salt-cured roe of the Acipenseridae family.
Caviar is considered a delicacy and is eaten as a garnish or a spread.
The roe can be "fresh" (non-pasteurized) or pasteurized, with pasteurization reducing its culinary and economic value.
Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (Beluga, Ossetra and Sevruga caviars).
Depending on the country, caviar may also be used to describe the roe of other species of sturgeon or other fish such as salmon, steelhead, trout, lumpfish, whitefish, or carp.
