I have 2/ 2 pound pkgs of mashed potatoes I bought from the grocery store. I find I won't be using both and wonder if I can safely freeze one of the packages?
Yes, of course you can. You can already buy frozen mashed potatoes at places like Trader Joe's. I would either freeze them in a gladware type of plastic container or put in a freezer ziploc and squeeze out as much air as possible.
