Caviar, round, full of particles, crumbles in the mouth and tastes fishy and salty. In a narrow sense, caviar is only made from sturgeon eggs, and caviar produced in Caspian Sea is the best.
In France, caviar refers specifically to sturgeon eggs, and is called the three most luxurious foods in the world together with foie gras and black truffles. It is also called "black gold" or "Caspian black pearl" because of its rare output and dark color. Caviar has no brand name, only grade and quality. High quality caviar comes from only one kind of wild sturgeon: European herring, Oseltra sturgeon and Flash sturgeon.
Caviar introduction:
The most famous origin of caviar is Russia or Iran on both sides of the Caspian Sea. Caspian Sea is the largest inland water area in the world and the hometown of sturgeon. The waters here contain special algae, which is the staple food of sturgeon. Fishermen catch female fish in spring and autumn and take eggs for caviar. Russia has the earliest history of fishing and hunting sturgeon. In the12nd century, Russian caviar was well known, and the French learned it from the Iranian emperor.
Caviar in the traditional sense refers to pickled sturgeon roe. Its value is equivalent to truffles in the plant kingdom, and it is expensive. It has long been a "luxury" on the western dining table.
