Sweet Migration serves up three unique stories about a family restaurant in Harbin serving a dish that's a unique fusion of southern and northern Chinese cuisines; a French bakery in Tierra del Fuego, Argentina; and a well-known doughnut shop in New York. As people move from city to city and country to country, they spread their culinary cultures. The program reveals the unique attraction of sweet food that allows it to transcend geographical boundaries to become a bond shared worldwide, a form of cultural expression, and a means of heritage preservation.
