The Solution to Crying With Onions...

My mother and I found the solution by accident (to tears with onions, of course).

Just put them in the refrigerator.

I'm serious. I still do that. And I have cried in years. Well, not due to onions, in any event.

 

Wola!​

 

Wouldn't work in the slightest. Neither does cutting them under water. Or holding a piece of bread in your mouth. But refrigerating them works like a charm every time.
