Theres an old saying that goes: when the going gets tough, the tough get going. And thats certainly true of southern cooks. Potato candy actually originated in the south during the great depression; making this tasty treat was a great way to create a delicious confection out of the little ingredients that were available during those trying times. This old-school candy reminds us of divinity and other traditional homemade southern sweets, but gets a little more creative. Complete with creamy peanut butter, powdered sugar, and vanilla extract, potato candy is the unique southern sweet thats sure to turn heads at your next family reunion, holiday festivity, or birthday celebration. The cold mashed potatoes, as the name suggests, are key in this recipe because they act as a binder, holding the candy's ingredients together. When preparing this nostalgic dessert, we recommend using the jelly-roll method. This method simply uses a piece of parchment paper as a guide to help you roll the confection into tight, beautiful layers.
