One way to peel an onion without crying is to first cut off the top and bottom of the onion, and then cut the onion in half from root to stem. Next, use a sharp knife to carefully peel the skin away from each half, starting at the root end and working towards the stem end. You can also try holding a match or a lit candle next to the onion while you peel it, as the flame can help to reduce the amount of fumes that are released. Additionally, you can try peeling the onion under running water, or even in a bowl of water, as this can also help to reduce the amount of fumes that are released.
