High on Dry
Using a food dehydrator is one of those kitchen activities that’s part cooking, part science project. With a gentle blast of warm air, you can turn slices of fresh fruits and vegetables into crispy, crunchy, vitamin-packed snacks.
The process is simple: a heating element acts as a low-temperature oven, while a fan circulates the warm air for maximum evaporation of moisture from foods. All you have to do is place the food on the dehydrator trays, set the temperature and timer, then check for doneness. There’s plenty of room for experimentation, such as seasoning sweet potato chips with rosemary or sprinkling fruit slices with cinnamon, as you’ll see in the easy recipes that follow.
4 Easy Steps
1. Arrange seasoned or plain sliced fruits and vegetables on dehydrator trays without overlapping.
2. Set the temperature. For foods to dry out completely and still be considered raw, the temperature should be set to 104°F. Cooks who aren’t concerned with the raw aspect may prefer setting the dehydrator to 135°F to shorten drying times.
3. Check regularly, and rotate trays. Dehydrating fruits and vegetables can take 2 to 19 hours, depending on moisture content and humidity in the air. To test for doneness, cut a slice. Food is dehydrated when no moisture beads appear in the cut.
4. Cool and store in an airtight container in a dark, dry place. If leftovers lose their crispness, return to dehydrator 1 to 2 hours to restore the desired texture.
