We've all heard it before: this TV chef shares a "must follow" tip for making pasta or this cook book touts the only way to properly prepare meat or your mother always told you the best way to fix over-salted soup. Yet you might be surprised to learned that these "words of wisdom" aren't always correct.
"There's a myth that you can add a potato to the soup and it will somehow remove the salt. Really, it's just adding a very bland substance to the soup, one that needs a lot of salt to taste right. Removing the potato at the end will remove liquid as well as salt without radically altering the balance. You might as well just add water, which achieves the same effect. Or you can go ahead and add the potato, and leave it in. Either way, you're basically just adding more soup to the soup to dilute the salt."
