Peeling and slicing onions always makes my eyes run and hurt like hell.  I've read ov various techniques to prevent this; peel them under water - but how do you then dice or slice?, put them in the fridge so they are cold, open the window etc.

I have, however, found the perfect cure! So simple, swimming goggles - ok, you look a bit odd and your other half might curl up laughing but it works (for me anyway). I can (and have) peel, slice, dice etc. loads of onions with absolutely no ill effects.

Try it for yourself or maybe you have some other method thet is worth trying....
