Chow-chow is a very old-fashioned sort of relish, although it is still very popular on the east coast, especially in Nova Scotia. It seems to have died out to some degree in Ontario, although it was once ubiquitous here too. Old cook books are full of recipes for it. The vegetables in it varied somewhat and it went by a huge number of names...

Green tomatoes: Chow Chow. A good way to use all those tomatoes I picked right before the freeze.
