Candied Orange Slices: Trim ends from 3 navel oranges; slice into 1/4 inch thick slices. In a large saucepan combine 2 cups sugar and 1 cup water. Bring to boiling; add orange slices. Return to boiling. Reduce heat to medium and boil gently, uncovered, for 12 minutes, gently stirring orange slices into syrup occasionally. Remove from heat. Preheat oven to 200 degree F. Line a very large baking sheet with parchment paper. Remove orange slices from syrup using tongs or a fork, reserving syrup. Arrange orange slices on prepared baking sheet. Bake for 1 hour or until oranges are translucent and candied, but still soft. Remove from oven; cool completely on baking sheet. Store in an airtight container. Transfer syrup to a small bowl and chill until needed.
