(I originally posted this March of 2009, it is still my most popular post, getting at least 5 hits a day and for a while was at the top of the google search for “canning potatoes”)
Last Fall I bought 150 pounds of potatoes at a really good price. I have been trying to feed them to my family and while we are potato people we just haven’t been able to eat them all. The nice thing about potatoes is that they store really well. We have a little room that says nice and cold in the winter, sort of like a little root cellar. There are a couple of flaws in our little root cellar, number one is that is doesn’t stay consistently cool as the weather warms up and number two it that there is a window in the room that lets the light in.

As the temperatures have been getting warmer and the days a little longer my stored potatoes have decided that it is time to sprout. That in itself isn’t a bad thing, you can still eat a sprouted potato for a while, it is an indication that their storage days are limited. I knew we couldn’t eat 75 pounds of potatoes before they grew leaves and went bad.

So I decided to can them. I have never canned potatoes before and up until a year ago I had never even heard about canning potatoes. I figured it was worth a try if it meant that I wouldn’t lose all that food.
I scrubbed my potatoes really well and washed them twice. I didn’t want to go to the effort of peeling them, usually we just eat potatoes with the skins on anyway, so I wanted to make sure they were really clean.

I then cut them into cubes and put them into a salt water brine, it helped keep them from turning brown while I was cutting up the rest of the potatoes.
Once I had enough potatoes to fill my two pressure canners, I loosely packed the potatoes into quart sized jars. I added a teaspoon of salt to each jar then filled them with warm water leaving about a half inch head space.
I put on the lids and processed them for 40 minutes at 12 pounds pressure. I added two pounds pressure because of my altitude, when using a pressure cooker you adjust the pressure for altitude, as opposed to the time as you would for cold water bath.

They were all boiling when I took the out and they sealed really quickly, the first batch was still boiling when I went to bed 2 hours later, and the last batch was still warm when I got up in the morning.

Here they are the next morning, cool and ready to store or eat! For breakfast I fried the potatoes with bacon, YUM! I processed 25 pounds of potatoes, it came out to 28 quarts…..I have 50 pounds to go!
****If you decide to can potatoes you have to use a pressure cooker, any other method is unsafe!****
(Up-date…..after the potatoes have sat for a bit the water will go cloudy, it is the starch from the potatoes coming out into the water, the potatoes are still good to eat, this will not affect the flavor or texture at all)
