While frustration alone can make you shed a tear when chopping onions, the actual reason you cry is due to the chemical irritant syn-propanethial-S-oxide.
You probably have your own way of quelling the tears — putting the onion in the freezer, lighting a candle, etc. — but what about the annoyance of actually chopping them evenly?
This little trick teaches you the best way to cut up an onion so you don’t have pieces all over your counter and floor…you’re about to become the onion-chopping king.
But if that doesn’t work for you, you could always do what this guy does…right?
