Crying over onions- a few remedies?

I was flicking through 'Carla Emery's Old Fashioned Recipe Book- An Encyclopedia of Country Living' that my Mum had picked up from the Book Barn a few years ago and I stumbled across an interesting entry.

Carla Emery had been told by some of her readers about a cure for the onion tears. I have never tried it before, so I would love to know if this is true. Next time someone is chopping onions I'll try to remember to ask them to test it.

• Keep a supply of onions in the fridge so that they are ready when you need them

Alternatively you could try:

• Putting them in the freezer 5-10 minutes before you need them. Apparently this doesn't effect their flavour or texture.

Or:

• Put a bread crust between your teeth, as it makes you breathe through your noes.
