Enter my amazing pressure canner!
Oh yes, you can can potatoes! Be sure to follow the directions that come with your canner, but it couldn't be easier. Simply clean & parboil the potatoes, and load into prepared jars leaving one inch of headspace. Fill the jars with a teaspoon of kosher salt and boiling water, pop on your lids, tighten the bands, and load 'er up. As I was using quart sized jars, a quick 40 minutes at eleven pounds of pressure and tah dah: I have five quarts of potatoes, ready for anything this winter throws at me.
Short, simple and sweet. It doesn't get much easier than that.
