Turn a candle on, onions contain a natural oil, yes, oil which contains
sulfur which is an irritant to both our noses and eyes. When we cut
an onion the gases within the onion propanethiol S-Oxide mixes with
the enzymes in the onion letting out a sulfur compound.
Basically, when it reaches our tear ducts and our eye lids,
our eyes start to water. Why turn a candle on?
The flame of the candle actually burns up the sulfur....
so it helps burn it up in the air before it reaches our eyes.
When you are dicing onions-
start with cutting it in half and laying the one side down.
and you want to cut in layers almost up to the end with the root...
almost in a grid like way...
and then when you slice it, the onion will cut in diced pieces...
