鱼子酱, or caviar, is a delicacy made from the salted eggs of fish, primarily from the sturgeon family. It is known for its rich flavor and unique texture, often served as a luxurious appetizer or garnish. The most prized varieties include Beluga, Osetra, and Sevruga, each differing in taste, size, and color. Caviar is typically enjoyed on its own or paired with accompaniments like blinis, crème fraîche, or toast. It is often associated with fine dining and special occasions, making it a symbol of luxury in many cultures. The production of caviar is highly regulated to protect endangered fish species.
