I grew up thinking that onion soup mix had magical powers. It transformed plain old sour cream into something that made me want to eat raw broccoli by the pound, it made casseroles have the most amazing flavor, it even tasted good just added to water (when I was a starving college student).

Well, over the years I have come to look deeper into the foods that I eat, especially when they come from a box or small white envelope. Alas, my magical onion soup mix was not so magical. It was full of the flavor enhancer MSG. Aw man! Just look at this ingredient list…
