A delicacy is a food item that is considered highly desirable in certain cultures. Often this is because of unusual flavors or characteristics or because it is rare. Delicacies are different across different countries and ages. 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, when they started being treated as they were in Europe, a delicacy.
