1. Peel Florida Grapefruit and Oranges, then slice into ¼-inch thick rounds. Arrange citrus slices, overlapping slightly, in a deep platter.
2. In a skillet, cook sugar over medium heat for about 10 minutes, swirling sugar in skillet until it begins to melt. Continue cooking and swirling until sugar melts completely and becomes a deep amber color.
3. Remove skillet from heat and drizzle caramelized sugar over fruit.
4. Serve immediately for a crunchy candy-like topping, or cover and refrigerate until caramelized sugar hardens, about 2 hours, or until ready to serve.
Variation: Thinly slice some Florida Grapefruit peel and sprinkle over fruit before drizzling with caramelized sugar.
