Chow chow

Chow-chow is a pickled dish popular in North America whose origins are unclear. Some suggest an origin from the American South, other sources suggest it originated in Canada and was brought south by the Acadians who migrated to the American South after being expelled from from the Maritimes in the mid 1700s, another theory is that it originated from Chinese railway workers. Made primarily of chopped green tomatoes, onions, cabbage, and seasonal peppers (though carrots, cauliflower, beans, and peas are sometimes included), chow-chow is a pickled relish eaten by itself or as a condiment on fish cakes, mashed potatoes, biscuits and gravy, pinto beans, hot dogs, hamburgers and other foods. An early 20th-century American recipe for chow chow was made with cucumbers, onions, cauliflower and green peppers left overnight in brine, boiled in (cider) vinegar with whole mustard seed and celery seeds, then mashed into a paste with mustard, flour and turmeric.
