Flamingo tongue was a highly prized dish in ancient Rome, but is not eaten at all in modern times. Lobsters were considered poverty food in North America until the mid-19th century[1] when they started being treated, as they were in Europe, as a delicacy. Some delicacies are confined to a certain culture, such as fugu in Japan, bird's nest soup (made out of swiftlet nests) in China, and ant larvae (escamoles) in Mexico.
