Peel oranges; scrape white pith from rind. Reserve orange sections for another use.
Cut rind into 1/4-inch strips.
Combine 1 1/2 cups sugar and 3/4 cup water in a medium saucepan over medium heat; cook 2 minutes or until sugar dissolves, stirring constantly. Stir in rind; cover, reduce heat, and simmer 3 minutes.
Remove from heat; cool completely. Strain rind mixture through a sieve into a bowl. Discard liquid. Pat rind dry with paper towels.
Place remaining 1 cup sugar and rind in a medium bowl, tossing well to coat.
