Wash three small oranges or tangelos under cool water. Slice each orange into ¼-inch rounds.

Combine three cups of granulated sugar and three cups of water in a large skillet over medium-high heat. Stir until sugar dissolves and mixture begins to boil.

Reduce heat and add orange slices in a single layer. Simmer for 45–60 minutes, turning occasionally.

Remove slices from syrup and place on a wire rack to air dry at room temperature for 24–48 hours.

Roll dried orange slices in granulated sugar or dip in melted chocolate for added sweetness and presentation.
