Preventing Tears When Chopping Onions

The tears from slicing onions can be so annoying. These tears are caused by releasing the gasses from the onion when it is cut and them making their way up to your eyes. Stop these gasses in their tracks just by sprinkling a bit of salt on your onion before chopping away. The salt dissolves the sulphur in the vapors. It also helps to use a sharp knife on a refrigerated onion, as less of the irritating enzymes will be released into the air. Happy chopping!

Before slicing or chopping an onion, put it in the freezer for about 45 minutes. It won't burn your eyes since the liquid will be partially frozen!

I have no idea why this works, just that it does. When chopping onions, hold a wooden spoon in your mouth and you never have painful, teary eyes.

When you are cutting onions, simply keep your mouth closed. Don't talk; and try not to breathe in too heavily.
