Onions Left Overnight


Hi, I chopped up onions and then realised I will be unable to prepare the dish until tomorrow. Is there any permissible way to leave onions overnight and still be allowed to eat them.


For onions left overnight, add in to the onions [even] a small amount of something else, such as oil, salt or sugar. Thus it is considered a mixture and not subject to this concern.


Sefer Shmiras Haguf Vhanefesh pg 25 cites a number of authorities who maintain that being that we are dealing with a spiritual danger whose nature and mechanics is not understood to us, we apply the rule only to the exact case it was taught on, i.e. without a mixture.
