Learn how to pressure can potatoes. If you grow your own potatoes then like me you probably end up with small to medium potatoes rather than large bakers. No ordinary homestead shares how to can the whole potato or diced if you prefer. Once canned she tells us the potatoes are great for mashed, home fries or in roasted recipes. Pressure canning will keep the potatoes from going bad for a long time. It is the perfect way to preserve those small potatoes.
