My BF grew up in Suriname and always (I Mean ALWAYS) rinses chicken and seafood with vinegar (red wine, white wine or cider, even plain white, really doesn't matter which). In fact, he'll ask me if I did the same when I do the cooking. Has anyone ever heard of this? At first he said this was due to cleanliness. Vinegar would kill germs (?). I then, rather obnoxiously, explained that chicken from the modern supermarket is not like grabbing one running around the streets of Suriname's capital city, and that FDA regulations will help deliver consumers a clean bird. So then he said it affects the 'texture' of the meat. I think it is a childhood comfort thing, or maybe cultural - the ladies he grew up with did it. Anyone ever hear of anything like this in other cultures?
