Prevent Onions From Making You Weep
To stop onion-induced tears, freeze the onion before chopping. Or if you want to look absolutely crazy when your housemate walks in,
put a Slice Of Bread in your mouth (partially sticking out) to absorb the irritant gas before it reaches the eyes
Note: This trick only works if you’re planning to cook the onions later—otherwise, after the onion thaws out, the raw pieces will be a bit soggy!
