Tips to chop an onion without crying?

Many people find chopping onions a dreadfully tearful task – even attempting it can be enough to make your eyes water! Fortunately, there are some tips you can use to help make the process of prepping an onion less of a crying game.

First, using a sharp knife is essential. Dull knives require more pressure which increases production of the irritant gas that makes us cry.

Secondly, you may want to chill your onion in advance so that it releases fewer compounds when chopped. Additionally, wearing goggles will protect your eyes from the compounds released from cutting and also allow more air circulation around your eyes.

Make sure to cut away from yourself instead of towards yourself and paying attention to your posture will prevent any accidental slicing mishaps. Cutting near a running tap or fan will help clear the air of these tiny irritants as well.

For those particularly sensitive to onion fumes, consider soaking the chopped pieces in salted cold water after they have been cut which helps to neutralize most of these compounds that cause tears.

Finally, as tempting as it may be, do not try to speed up the process by rubbing or quickly rinsing your hands with water afterwards! Onion juice is known for lingering on our skin and potentially finding its way into our eyes – resulting in some good old fashioned crying time! All these measures combined should have you chopping onions with ease!
