I just got a dehydrator and am planning to dry lots of fruit. When I flipped through the recipe book that comes with it, they talked about pre-treating the fruit in some ascorbic acid mix before drying it. They're trying to stop it from turning brown, I think. Does anyone have any experience with dehydrators? I don't really care if the fruit turns brown, but I do want to make sure that the flavor and texture of the dried fruit is really good. Any suggestions on how I should proceed?
