This was sent to me by a resident of Guam via an online gaming community. It is intended to be made in a rice cooker. Refer to your manufacturer's directions for the correct amount of liquid to use with this quantity of rice.
When I was in Hawaii, the hotel I stayed in always had a large dispenser of this water in the lobby, to help rehydrate the guests after they spent too much time on the beach. I found it to be much more refreshing than plain water, as the fruit adds a very subtle sweet taste. A great recipe if you're trying to get more water into your diet. This will not taste like fruit juice, it's meant to be a very lightly flavored water. If you don't have a large drink dispenser, try making 1/2 recipe in a sun tea jar.
