Using a channel knife, cut long strips of peel from orange.
In a medium saucepan, bring 1 cup water and 1 cup sugar just to a simmer over medium-high heat, whisking to dissolve sugar. Add orange peel, and cook for 10 minutes.
Using tongs, remove orange peel from syrup mixture. Lay flat on a wire cooling rack. Let stand over- night to dry.
The next day, wind orange peel around a drinking straw to curl. Store in a covered container at room temperature for up to 3 days.
Just before using as garnish, snip into desired lengths with kitchen shears. Toss curls in remaining ¼ cup sugar, if desired.
