Served up with a mother of pearl spoon and alongside a crystal flute of champagne, caviar is the ultimate culinary symbol of wealth, luxury, and decadence. But how did tiny fish eggs—which many might regard as an unwanted, throwaway food—become such an international delicacy? In Caviar: A Global History, renowned food writer Nichola Fletcher answers this curious question, examining the rise of caviar as an indulgence and its effect on the lives of the people who seek and sell it today.            Fletcher takes the reader on a tour of the main areas of caviar production—Russia, Iran, Europe, and America—and investigates how the industry has contributed to the decline of the sturgeon population, the fish most associated with caviar.
