Chow-chow (food)

Chow-chow (also spelled chowchow or chow chow) is a pickled dish popular in North America whose origins are unclear. Some suggest an origin from the American South, while other sources suggest it originated in Canada and was brought south by the Acadians who migrated to the American South after being expelled from the Maritimes in the mid-1700s; another theory is that it originated from Chinese railway workers.
