Combine lemonade, tea and whiskey in a cocktail shaker with ice. Shake, then strain and pour over ice. Garnish with sprig of rosemary.

How to make Rosemary Lemonade:

First, make rosemary simple syrup by placing water, sugar and rosemary springs in pot and bring to a slow boil. Turn off the heat once sugar dissolves, cover and let infuse for 30 minutes. Once cool strain into a container to store.

Add rosemary simple syrup to lemonade to your taste.
