2 cups berries, fresh or frozen
1 cup beets
1/4 cup honey—less based on your preference
1/2 cup water—adjust based on need
Prepare your beets if using fresh. Peel them & then steam or roast them. Let cool until you're ready to use them.
Combine berries & beets in a blender & blend until you need to start adding water. Slowly add in water until you reach the desired consistency you want. It should be like a custard.
Slowly add honey (if desired) until it's as sweet as you like. Remember that dehydrating fruit brings out extra sweetness as well!
For a Food Dehydrator:
Lightly oil the fruit roll sheets with a little oil of your choice. Pour into two fruit roll sheets on dehydrator trays. Spread with a spatula. The mixture should be about ¼ of an inch thick. I prefer too thick to too thin. Be careful to make sure the mixture is spread evenly. If you can see thru some areas of the fruit sheets, as the leather dehydrates, you will have tears. It doesn't affect the taste, just the appearance.
Place in dehydrator for 2 hours at 160. After 2 hours, you can turn down to between 130-140 & continue to dehydrate for 5-7 hours, checking frequently. If the leather feels squishy in spots it's not done. It should peel easily & feel dry. You will definitely feel if the leather is too dry as it will become brittle & start to break when you peel it up.
In the Oven:
Line a 12-by-17-inch rimmed baking sheet with a silicone mat or nonstick foil. Use an offset spatula to spread the fruit on the mat or foil into a thin layer. Bake on lowest temperature until barely tacky, 3 hours to 3 hours, 30 minutes.
Transfer the baking sheet to a rack and let the fruit leather cool completely. Peel off of the mat or foil. If the leather is still moist on the underside, return it to the oven, moist-side up, until dry, about 20 more minutes.
Once leather is dry, remove & cut with scissors into strips or squares.
