Potato candies may have come from Germany, France, Russia or Ireland€”probably all these places in different forms in the late 1800s. Potatoes have long been used as a starch so the potato flavor vanishes when the candy is made. The addition of peanut butter is purely American. The potato candy was popular from the start but took off during the Depression and has been an Appalachian hit ever since. The expiration date is approximately two weeks depending on the weather, so best to eat right away! Comes in a tub of six, with the history on a tag.
