Stir together with a large wooden spoon to help the sugar dissolve.
Refrigerate for at least 4 hours before serving.
Serve chilled with a garnish of rosemary sprigs. Make sure to get some of the fruit in every glass!
Notes
*Note that the original recipe used granulated sugar instead of simple syrup. If you prefer to use sugar (or don't have simple syrup on hand), use 1/4 cup granulated sugar in the recipe. Be sure to stir the mixture well until the sugar dissolves in Step 2!
