Caviar is a delicacy consisting of salt-cured fish-eggs of the Acipenseridae family. 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 and Black Sea (Beluga, Ossetra and Sevruga caviars).
