Potato Doughnuts

Is there anything in the world better than a fresh, warm doughnut? Okay, so maybe they are not so good for us, but every once in a while you definitely need one. Have you ever tried making your own? Mom would make them with canned biscuits and sprinkle them with sugar. Sometimes though, she would make them with leftover mashed potatoes. Yes, you heard me right, potatoes. She even had a special doughnut cutter. Of course, the holes were the best part! If you've never had a potato doughnut, try this vintage recipe sometime.
