Caviar is a true luxury delight and one of the most precious edible delicacies. It may come as a surprise, but caviar was once widely used as a popular and common food. Today it is a pleasant treat and even a status symbol. Caviar originates from the shores of the Caspian and Black Seas: Azerbaijan, Iran, Russia and Kazakhstan, where it still represents one of the typical dishes of local cuisine. It is often served as an aperitif on buttered toast.
