I hate cutting onions. Seriously, I hate it. It makes my eyes burn and I always tear up. I go to extreme measures to insure my eyes won't hate me by the end of my onion chopping. Here are some of my tips - be sure to share your own!
Cut it properly
Use a candle
Set a lit candle near the onion you're chopping. Apparently, the gas emitted from the onion is drawn to the flame.
I tried this with a tea candle and it didn't work very well. Make sure the candle you're using has a bigger flame.
Keep your lips closed and breath through your nose
When you're chopping onions, you should keep your mouth closed the entire time to prevent tears. I don't know if that's just an old wives tale or not. I'm not sure what the science behind it is either. I do it anyway and it actually seems to help!
Don't be a fool and chop with your eyes closed. That's never a good idea (for obvious reason) but I find that squinting helps. When you need to open your eyes fully, look away from the onion.
I've read that wearing contacts while chopping onions helps create a barrier between your eye and the gas omitted by the onion. Sorry, but I call BS on this one. I've worn contacts while cutting onions and I still tear up. What's worse is when I take my contacts out: my eyes burns!
