Syrup: In a saucepan, combine sugar, lemon zest, and 1 cup water. Bring to a boil over medium heat, stirring until sugar has dissolved. Remove from heat; let cool completely. Strain, discarding zest; stir in lemon juice. Cover and refrigerate in an airtight container until cold, at least 1 hour and up to 2 weeks. Makes 2 cups.
