Thats the nice thing about being a prepper for long time and putting this stuff aside, is that you finally get to test some of this stuff out to see what lasts
dried powdered cheese is another one..I store some in different ways to see how long the cheese would last and which way was better...
First off I highly reccomend that you do not save the cheese that comes in mac and cheese boxs, those went bad right after the expiry date..but I had bought some dried cheddar cheese at the bulk store, some I did up in canning jars with pump and seal and some I did up in zip lock sandwich bags(removed as much air as possible) and then I had some cookie tins, filled those with the zip lock bags and replaced lid and duct taped, dated...both ways were good in preserving the dried cheese..we are using the dreied cheese now for the boxed mac and cheese...I had to throw out all the little packets that came with the boxed stuff
