This lightly tart pomegranate-flavored mixer adds color and sweetness to drinks. For a tarter syrup, simply decrease the amount of sugar here by half.
In a medium saucepan, simmer the pomegranate juice with the sugar over moderate heat until thick enough to coat the back of a spoon, about 15 minutes. Add the orange flower water. Refrigerate in an airtight container for up to 2 weeks.
