Ketchup seems iconically American, but the word comes from a Southeast Asian anchovy sauce, and today it is made largely from Chinese tomato paste. Japan's beloved ramen arose from the meeting of Chinese noodles and American wheat flour before attaining worldwide popularity in both gourmet and convenience-food forms. Telling these tales and many others, What We Eat explores world history through the lens of the global journeys of nearly ninety food products. Leading historians trace the origins and popularization of items commonly found in supermarkets, showing how each food illuminates wider histories.
