Whether you're going to chop, mince, slice, roast, or grill onions, you're probably going to want to peel them first.
Yet peeling onions can, indeed, make one cry. The older the onions—that is, the longer they've been in storage since being harvested—the more they tend to make people cry when they're cut. Between the tear-inducing sulfoxides they release when cut and the often difficult-to-remove paper-like skin, peeling onions can be a bit of a pain. There is a simple solution to both problems, however: peel the onions under running water. The water rinses away the sulfoxides as they're released and it loosens the skin, making it easier to peel.
