Osetra Caviar is a type of fish roe harvested from the Osetra sturgeon, primarily found in the Caspian and Black Seas. Known for its rich, nutty flavor, Osetra caviar is considered one of the finest varieties available. The eggs are medium-sized, ranging in color from golden to dark brown, and have a firm texture that provides a delightful pop when eaten. This delicacy is often enjoyed on its own or served with accompaniments like blinis and crème fraîche. Due to its high demand and limited supply, Osetra caviar can be quite expensive, making it a luxury item in gourmet cuisine.
