The first step is to choose the food that you want to dehydrate. You can dehydrate almost any type of food, but some work better than others. Next, wash and slice the food into thin pieces. Then, place the food in the dehydrator and set the temperature. Dehydration times vary depending on the food, but typically range from four to 12 hours. Check the food periodically to make sure it's not overcooked or burning. When it's done, remove it from the dehydrator and store in an airtight container. Enjoy your homemade dehydrated snacks!
