Fresh onions can make you cry when you slice them due to a specific kind of acid — if you cut our white onions under cold running water, you can avoid the tears. Usually enjoyed chopped, onions are a hearty ingredient in soups and stews, and can be cooked in a wide variety of ways. Used raw, onions are an amazing ingredient in salads or on top of a burger. And if you get onion breath, just eat some parsley for a quick, natural solution.
