You can substitute your favorite herb or spice to flavor this simple, or sugar, syrup. The syrup may be used to flavor and sweeten lemonade or iced tea.
In a medium saucepan, combine the sugar with 2 cups of water. Bring the mixture to a boil over medium-high heat. Add the fresh herbs or rose petals to the syrup, remove the pan from the heat, and let the mixture steep for 2 hours. Strain the syrup in a sieve, and discard the herbs or rose petals. Store the syrup in an airtight container in the refrigerator for up to 1 week. Transfer the syrup to a small pitcher, and serve with unsweetened lemonade.
