👉 Caviar is a type of fish that has been prized for its taste, color, and texture. It is often associated with luxury and fine dining experiences, as it is considered to be one of the most expensive and rare seafood in the world. Caviar can come from a variety of species, including hake, mackerel, and cod, but it is particularly popular for its creamy white flesh, which is often served chilled or at room temperature.
