My Grandma used to make potato candy when I was little. You boil a small potato and drain it well. Mash with a fork and stir in enough powdered sugar to make a stiff dough. Roll out like pie crust and spread a good layer of peanut butter on it then roll up like a log. let stand for a little while then slice crosswise into pinwheels. You would never guess it was made with a potato. It was always a big treat for us when we were kids. Hope you all enjoy!!
