Despite the fact that housewives chop onions almost every day, it is not always possible to protect against the appearance of tears.
Don't rely on luck: it's better to use proven tricks from chefs that will help make the task easier.
There are several options for using cold temperatures, each with its own effectiveness. Some people put the onion and knife in the freezer for a short period of time.
Others use the refrigerator itself for this purpose, but increase the exposure time.
There is a third option. You need to hold the onion with the knife under a stream of cold water. You can also pour water into a bowl and place it next to the place where you work with the onion.
This trick may seem strange, but for some reason it works for many people. All you need to do is take a mouthful of water and not swallow it until you are done with the vegetable.
Chewing gum has a similar effect.
