Step by step, the easiest way to chop an onion

 

Onions are in almost everything we eat (except deserts of course). They can be caramelized, chopped and added as the base of many dishes, sliced thin, or even made to look like a flower.

Today we are going to look into a technique to chop an onion fast, safe and effortlessly. You’ll be all diced before your tears decide to fall out! Hint: whenever you chop strong onions, which in my case is any onion because my eyes are really sensitive, I can usually stop the tears when I turn on a faucet and put my head above the faucet. Maybe it clears the fumes or maybe I’m crazy. Another, slightly more drastic thing to try, is some onion goggles. Yes, really. These exist as a thing that you can buy. Ha!

Another way to prevent tears from onions is to use a sharp chef’s knife. The knife will cut through the onion cell walls evenly, resulting in less onion fumes being released. On to the chopping…

Step#5

Once the onion is peeled, take one half and place it on the cutting board. Make vertical cuts making sure to leave the root intact. I cut each slice about 1/4 inch.
