...is to rotate your stock.
I have a decent supply of food stores for my friend Justin Case. This past weekend we converted one of our coat closets into a food storage closet to make rotation easier. I have been doing a good job of rotating the canned goods from under the beds in the guest rooms, but the cans in the harder to get to places did not get rotated out.
We have some pretty old canned goods to go through. The oldest is 20 months past the "best by" date. This is a very small percentage of what we have on hand, but disappointing never the less. Note for future reference: 20 months past the best by date is still edible, not tasty, but edible.
This is just a reminder that if you put up food for Justin Case, remember that it is important to rotate it out. Store what you eat and eat what you store. If you get behind, V will make you eat it anyway.
