On how to store cut onions by Mother Google...

I needed to know how I should store cut onions...I couldn't call up my mom for this..so I turned to Google...

And this is what I found:

Once you cut an onion, wrap whatever portion you don’t use in plastic wrap, and put it in the refrigerator. It will keep about 4 days.

see, how simple...look ma, no phone calls, just googling...
