We bought forty pounds of potatoes a week and a half ago. Today we finally got a chance to can about fifteen pounds of them (give or take). After peeling them, we diced and boiled them for five minutes. We put potatoes in quart-sized jars, poured in boiling water, and then processed them for 40 minutes in the pressure canner. We ended up with fourteen quarts of diced potatoes.
We make a lot of soups through the winter and it will be so nice to just open up a jar of potatoes and pour it into the soup. Yum!
A big bonus is that we didn't add any salt, so we can use these and not add to the sodium content of our meals - something that we keep track of in our family for health reasons.
We still have a twenty pound bag of potatoes and I hope to can ten or fifteen pounds of that.
Another thing I want to try in the future is opening a jar and draining it, and seeing whether or not it'll work to use them for mashed potatoes.
