Tell us about yourself!
So much time spent on assuring you have no tears.I think the point is to get skilled enough to cut your onions quickly to avoid the tears...or just deal with them, its not that bad.I have never seen a chef prepare onions for this purpose.
Actually, storing onions in the fridge makes them spoil quicker. While it 'seems' they keep longer, they aren't.Onions need air circulation and a dry area to maintain the dryness of its protective skin. I keep them out in the open on the counter.
