No recipe just make mashed sweet potatoes add maple syrup, cinnamon, nutmeg and a little apple juice to get it to consistency but not too runny. I do it to taste. No butter or fats. Then spread it on trays in your dehydrator. I like to use parchment paper for this because with the syrup it can be sticky and less clean up. Then dry just like fruit leather or I like to dry mine beyond that to a stage that it can break apart (crisp) and put it in mason jars as a bark. I break in chunks and put in jars with oxygen absorber. As a bark it just kind of melts in your mouth over time almost like a piece of candy. I used to make it for my boys for backpacking when they were boy scouts. They would eat bags of this and homemade jerky.
Thank you DD! Sounds fabulous and I will try it!
