Potato to Bark
Snack on potato bark like a chip while hiking or turn it into mashed potatoes for the evening meal. Create an unlimited number of thick and flavorful one-pot meals by combining potato bark with dried ham, chicken, or ground beef plus dried vegetables of choice. Enjoy plain with salt and pepper or blend additional flavors into it such as barbeque sauce.
Ingredients:
2½ lbs Potatoes
16 oz. Fat Free Vegetable, Beef, or Chicken Broth
Salt and Pepper to taste, Garlic Powder optional
Yield Dry:
2½ pounds of potatoes yields approx. 2
cups bark weighing 5½ ounces.
Peel and boil 2½ pounds of potatoes until soft. Drain.
Mash potatoes with 16 ounces of fat free vegetable, beef, or chicken broth. Because
fats and dairy products don’t dehydrate well and can spoil, do not add any milk or butter. Add salt and pepper to taste and garlic powder, if desired.
Run the mashed potatoes through a blender until creamy.
Barbecue Potato Bark Variation:
Substitute 8 oz. of barbeque sauce for 8 oz. of the broth. This will give your meal a fl avor like Brunswick Stew.
Dehydrate:
Cover dehydrator trays with Parafl exx® non-stick sheets, parchment paper or the fruit leather inserts that fit your model dehydrator.
Pour a six inch puddle of potatoes and spread about an eighth inch thick with
a spatula. Try to keep the thickness as equal as possible so that the potatoes dry evenly. 2½ pounds of mashed potatoes spread thinly takes up five 15 x 15 Excali-bur trays.
Dehydrate at 135° until potatoes form a brittle sheet, about 8+ hours. Potatoes
spread thickly or with uneven thickness will take longer to dry, but given a few
more hours will turn out fine.
After about six hours of drying, peel the potato sheets off trays and flip them over so that the moister bottom side gets exposed to airflow for the last few hours of drying. If the potatoes don’t peel off easily, wait a little longer before
flipping them over. Dried sheets of potatoes will easily snap into pieces for packing.
