How to Make It
Remove rind from orange with a vegetable peeler, being careful not to get the bitter white pith. Set orange rind aside. Squeeze orange to get 1/2 cup juice.
Combine orange rind, juice, and sugar in a small saucepan. Cook over low heat, stirring until sugar dissolves. Bring mixture to a boil over medium-high heat, and boil 2 minutes.
