Where I grew up, it didn’t matter if you were black, white, latin, whatever. You went to have lunch at least once a week at a restaurant in a rough part of town called (appropriately enough) Soul Food. I was a lower-middle class white kid, born to a mother who had grown up poor. Growing up, her parents (who were huge influences on me) had raised a little livestock (enough for them to eat/get milk and eggs/whatever from, not as a business), grown their own food, and cooked what anyone who didn’t know my Nanny was an anxious old white woman, would be called soul food.
