Zest one orange.

Juice the oranges.

Stir the sugar into the water and heat on low until sugar dissolves. Set aside to cool.

Combine sugar water, zest, and juice in a 9x13 baking dish.

Freeze for an hour, scrape with a fork to form crystals and refreeze. Repeat until no juice remains and crystals have formed.

Using your fork, scrape and fluff the pan and add ice crystals to a serving dish.
