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!
Top and tail the onion without removing the outer skin. Halve it top to bottom, and place each half cut side down. One half at a time, remove the skin and chop or slice the onion, still "cut side" down. That's all. Doing that will avoid streaming eyes almost entirely. Mine have been free of it for many years.

I have found that it helps me when I am cutting onions to wear swimming goggles. I also have to keep my mouth closed. I am a great onion fan, but my eyes hate them, because they burn really bad. The goggles really help me. Either the small ones like eyeglasses or the huge ones help keep me from tearing up when I slice onions which is almost daily.
When you are cutting onions, simply keep your mouth closed. Don't talk; and try not to breathe in too heavily. Worked for my mom when she discovered the trick andit works for me too.
Best to all of you.

I love cooking and cook all the time, often with either onions (red preferred, but using any often) or garlic. My complaint (and question in one) is how do I keep from shedding tears when cutting onions (and sometimes really strong garlic)? It wouldn't be so bad if the tears weren't falling fast (sometimes) and the burning that follows. Help. Please.

There are two more suggestions below that I haven't tried and hope they will work. I do know how to get onion and garlic smells off your hands though. Just run your hands under cold running water and rub a stainless steel spood around your hands. You probably have heard this one before!
I'm going to monitor your question and see who comes up with more solutions. Good luck to you. (10/14/2009)

Number One: keep them refrigerated in the crisper
Number Two: Cut off the top and bottom,peel outer skin off, cut them in half lengthwise, turn both cut surfaces down on your cutting board so that only the smooth round skin side is facing you.Now,hold one half down on the cutting board with one hand and slice lengthwise in strips almost all the way to the root end,holding slices together,then and only then do you slice across the ridges.Repeat with the other half.
This causes all the oils to be released down into the onion, with the least friction;therefore,less irritants are released to go up your nose and in your eyes. (10/15/2009)
Keep onions in the refrigerator for 4 days to stop tears when slicing onions. This is a tried and true tip.
