This is an easy and bright addition to the Thanksgiving menu that doesn't require any cooking.
Place the sugar, 1 cup water, and the orange juice in a medium saucepan over medium heat. Stir until sugar dissolves, about 5 minutes.
Add cranberries; cook just until berries start to pop, about 15 minutes. Remove from heat, and stir in orange zest and segments. Cool, and refrigerate overnight.
This relish is best made a day in advance.
