Did you know that you can whip up some of your own buttermilk at home? Most people don't like taste of buttermilk alone but it can taste great when used as an ingredient in red velvet cake and many other recipes. Buttermilk actually doesn't contain any butter at all. It's a mixture of distilled vinegar and milk. It can give recipes a little edge that they wouldn't normally have without the kick of vinegar. A long time ago buttermilk used to be the milky liquid that is left after homemade butter was made. Back then it was used as a facial cleanser as well as an ingredient.
