The title might be slightly misleading because there is no "one size fits all" list of things to have in your food storage.
The way I see it though, this is important.
Potatoes is what I am speaking of.
There are entire diet plans based around potatoes, simply because of how deceptively filling they are for how relatively few calories are in them.
The reason this is a good thing, rather than bad, is because if you are like me, you do horrible work when you are hungry. I have a long list of ex boss's who can vouch that.
In an emergency, especially of extended time, the truth is, you might be forced to cut back on rations. In my case instead of 4 or 5 meals a day I would maybe only get 2 or 3.
This is why say potatoes are important. If you are only going to get a certain amount of food, you might as well extinguish the "hunger" factor.
So now for the "how to".
Potatoes are slightly different than other things i have dehydrated. They take some prep work, rather than slice and dry.
Step 1: Wash, Peel.
Step 4: Steam them. This is how I did it but in this scenario, there is more than 1 way to skin a cat.
Load the bottom tray of a pressure cooker with potato slices, add a few cups water to the cooker, use something to set the tray on above the water, I used a colander. Turn the burner on, and let the potatoes sit in the steam just long enough to make the surface slightly cooked, and slimy, almost.
Step 5: Lay the slices on the dehydrating racks and let it go. I was surprised how quickly these dried, in just under 7 hours.
Final product, you can see they are slightly yellow, no surprise, I used yellow potatoes, but all varieties work the same way.
These would work great in soups, mashed potatoes, or any sort of potato casserole that you can come up with. To reconstitute, simmer in water for 10-15 minutes.
