3/22/2008: If you’ve ever thought about keeping an emergency stock of food for “just in case,” such as in a motor home or camper, let me tell you about one item NOT to include if you live in a climate that freezes: canned potatoes. We’re cleaning out our motor home to sell and using up the food that was stored in it.  Anything in there has been there over a year, including in temps down to at least -10 F.  Sealed items like sugar were fine; so were unopened items like pasta.  But oh, those canned potatoes did NOT survive in edible condition.  I opened a can today to make a potato casserole, and they were the exact consistency of jellyfish that had been left in the sun and then rained on.  Blech!  Straight into the trash.  (The canned milk wasn’t in great shape either.)
