Garnish with a fresh blackberry and sprig of rosemary
Instructions
To make syrup:
In a small saucepan, combine blackberries (no need to thaw if frozen), rosemary, water and sugar over medium-high heat. Stir until sugar dissolves while pressing blackberries against the side of the pan.
Bring to a boil and let boil for a minute.
Remove from heat and let steep for an hour or two so flavors can develop.
Strain syrup into a storage container.
Store for up to 2 weeks in the refrigerator or freeze.
To make cocktail:
Fill highball glass with ice.
Add rum and blackberry-rosemary syrup.
Top with seltzer and stir.
Garnish with a fresh blackberry and sprig of rosemary.
Notes
* The syrup recipe makes about 1-1/2 cups (or 12 ounces) – enough for 12 cocktails. * This syrup freezes well so you can make it ahead of time. * You can use white sugar in place of Turbinado (raw) sugar if prefer. * Great as a mixer for cocktails but also mixes well with seltzer.
