I volunteer with a group that cooks community meals and everyone knows that I'm the worst person to ask to chop all the onions because they irritate my eyes like absolutely nothing else- much worse than anyone else. Although if I have to do it the fact that it affects me so badly is a source of much amusement, of course. I know it happens to all of us, but within about a second of cutting into one my face will be streaming with tears, and my throat and nose start to burn pretty badly. In fact almost the same thing happens even if someone else is cutting the onions on the other end of the table, or if there's a bowl of chopped onion around me. I have to wash the cutting board and knife after or I'll still be "crying" while preparing the rest of the vegetables. One girl mentioned that the same thing used to happen to her but after a while she became desensitized, because she cooked with onion so often. No idea if that's true. At home I've tried chilling onions before cutting them, using sharper knives, etc, but nothing seems to help it. Do different people just have varying degrees of sensitivity to this effect of onions? Silly question maybe but I am curious.
