If you have a pressure canner, why not 'can' jars of potatoes for later use? That way they last for a few years if you don't need them. We peel and then cut into big chunks, then fill the jar and add salted water to the last 1/2" below the top. After canning we can store them and use them in recipes all winter. I love being able to open a jar of canned potatoes for a soup or stew, because they are already mostly cooked!
