Great to know as I'll be cutting up bunches of onions to put into the freezer for soups this winter. Right now they're braided and hanging in the back garage till I have time..........usually around January or whenever it gets too cold to have them out in the garage.........its insulated but not heated.
I also heard if you cut off the root end 1st you won't cry either. I rarely have problems with tears while I'm cutting all the onions, usually a 4 hrs session.
