TikTok has become a hub where “life hacks” are shared online. Here you can watch short videos and actually learn from them. People have been sharing hacks that actually work. And those who love to cook, want to talk about food and how they can make preparation so much easier.

Recently, TikTok users have been praising the originality of this cookbook author and nutritionist’s “life-changing” way to quickly dice an onion. If you don’t like slicing onions because it makes your eyes hurt and tears up, then you need to learn from this hack.

From My Little Kitchen, Melanie Lionello of Melbourne, Australia, shared her technique on Instagram and TikTok. People swear that this is a fool-proof way of slicing onions without making your eyes water.

In Lionello’s post, she wrote: “I was today years old when I learned that I could dice an onion like this. Please tell me that I’m not the only one.”

The video has been viewed more than 4.5 million times on TikTok and liked by more than 700,000 people on Instagram.

It’s a short clip showing how to do this trick. In the video, Leonello can be seen taking an onion whose peel and stem have already been removed so that one end is flat. She then lays the onion onto a cutting board with the root side up. She starts cutting up the onion into vertical pieces, starting at the bottom and working her way up.

Finally, she turns the vegetable upside down and vertically chops it again. After doing this all that was left was a perfectly diced red onion.

But why do these onions make you cry?

Experts say that when you chop onions, they release a chemical compound that irritates your eyes and triggers your tear glands.

The sulfur in onions is responsible for their unique, pungent odor. But sulfur isn’t the only thing that’s making you cry even when you’re not sad. When an onion is sliced, an enzyme called synthase combines with sulfur to form syn-Propanethial S-oxide.

The volatile nature of this compound causes it to release a gas that is carried by the wind that may reach around your eyes. This then activates the lacrimal gland and that’s when the floodgates open.

There’s no real danger behind the compound that makes you cry. In fact, it’s just an irritant. The pain you feel in your eyes as you cut up onions might scare you, but in reality, you will never go blind prepping food that involves onion cutting.

Aside from this hack, there are other tricks you can use to ensure that you don’t tear up when you are slicing onions. To prevent this reaction, you do the following:

The cells in the onion will be damaged less if you use a sharp knife to cut it.

Cool the onion in the fridge to prevent the lachrymator from scattering.

Soak it in water to dissolve the amino acids.

Protect your eyes with goggles.

Use a fan while cutting to blow the allyl sulfide away.

So the next time you cut up some onions, make sure that you try these hacks. They are easy to follow and will definitely make your life easier in the kitchen.
