How do you prevent tears while cutting onions?

I try to keep my head up as high as possible away from the onions. Some people wear safety glasses or swimming goggles.

I partially freeze the onions.

Dipping them in cold water as you work helps.

I really don't have a specific method to prevent tears while chopping them.

i've read somewhere that it's the middle part that makes us cry and that we should try to avoid it when cutting onions. i try to stick with that rule - and i usually don't cry

Thats an easy one ! There are many ways but I will share the simplest and easiest one. Soak the onions in a utensil/container filled with water. Next , cut the onions while they are submerged in water. This would easily prevent all tears as all the tear producing components would be dissolved in water. The only thing you would have to worry is cutting the onions in the container/utensil.It is not easy at beginning to achieve the same. There will be resistance from water for the free movement. And do one onion at a time in the beginning and that should help you master the trick. But once you have mastered it , it is easiest way to prevent tears. Try and do let me know. Good luck!

I just let the tears flow.
