No More Tears: How To Cut Onions So They Don’t Sting Your Eyes

Fresh onions are an insidious product that makes many housewives cry while slicing them. This is because when you cut an onion, it triggers a series of chemical reactions. Eventually, a gas is released, it evaporates, reaches your mucous membranes, and turns into acid, which irritates the lining of the eye.

What to do if onions make your eyes very stingy – effective tips

In order to avoid shedding tears and rubbing your eyes while cooking fresh onions, try to get rid of the burning:

  • light a fire – a burning burner or fire creates a flame that reduces the concentration of substances that irritate your mucous membranes;
  • pour cold water – take a deep container, dip onions in ice water, and chop them right there;
  • use the microwave – put the onion in the oven for 25-30 seconds, then the concentration of tear-inducing substances in the onion will decrease;
  • freeze onions – put an onion in the freezer for 10-15 minutes, then quickly slice it before it has time to warm up;
  • chew gum – when you chew menthol or any other gum, you exhale with your mouth, so it is difficult for the tear-enhancing substances to reach the mucous membranes;
  • pour boiling water – put a glass with boiling water next to you, then the steam will reduce the concentration of irritants in the air;
  • soak the onion – leave the vegetable in cold water for 5-10 minutes, this method will help “wash” the irritants out of it.

There is another interesting option – put on swimming goggles and chop the vegetable in them. Of course, it may seem strange, but it’s effective – you just protect your eyes from onion vapors.
