when I did flylady in 2000-2001 I found stuff in my cupboard seven years past the pull by date.
Yesterday I was getting out the penne pasta and found a package of Bob's Red Mill cracked freekeh, one of their ancient grains offering, it was in wide use about 4000 years ago.
I have no idea what my plan was, why I bought it. This is how the cupboard oldtimers get started...
On the other hand I leave my marshmallows and Peeps open because they need to be ripened to be edible, chewy like taffy, the older the better!
