Dried watermelon tastes very sweet, with a concentrated watermelon flavor that is still reminiscent of fresh, watery watermelon.
The dehydration process intensifies the natural sugars in the watermelon, resulting in a much sweeter taste than its fresh counterpart. While the water content is removed, the essential watermelon flavor remains, although it's more concentrated. Imagine a watermelon candy, but with a more natural, less artificial taste.
