I don’t know about you, but “eat what you store and store what you eat” sounds kind of… well, impractical.
Here’s the problem: there are always thing I will prefer to eat fresh if I have the choice. Like milk, for instance. No way am I going to switch to dried milk in the interests of “rotating my stores.” But if the “Big One” earthquake hit, I might be willing to hold my nose and get used to the taste. (Or give it to a neighbor with kids if I found I really couldn’t hack it.)
