Dehydrated fruits are a popular and handy snack, but you can save money by easily drying them yourself at home using your oven. Use the freshest produce for the tastiest results. Tip: use firm, less watery fruits for best results, such as apples, pears, and grapes.
First, wash the fruit and remove seeds and skin, then slice thinly and uniformly â€“ a food processor or mandoline will make easy work out of this. For fruits that brown easily, such as apples, soak them in lemon juice for about 5 minutes.
Next, set your oven on a low setting—about 100-150 degrees is ideal (any higher than 150 degrees and the fruits and vegetables will cook). Spread your fruits on a baking sheet in a thin layer, then place inside the oven. Be sure to leave the oven door partially opened to allow steam to escape. Fruit will be in the oven for 6-12 hours; it is done when the fruit is dry, seems leathery, and no beads of moisture form if you tear it in half. Store fruits tightly sealed in a cool, dry place.
