Step 1

To make the rosemary simple syrup: Combine the water and sugar in a small saucepan set over medium-high heat. Bring to a boil while stirring occasionally to dissolve the sugar. Allow the mixture to boil for 5 minutes then remove from the heat and drop in the sprig of rosemary. Allow the rosemary to steep for about 15 minutes and then discard the rosemary. Pour the simple syrup into a glass jar or bottle, cool to room temperature, cover, and refrigerate.

Step 3

To make a small batch: Pour vodka, lemon juice, and simple syrup into a drink shaker filled with ice. Cover and shake well to blend. Divide drink mix between 2 rocks glasses filled with ice, straining the ice from the shaker as you pour. You'll only want to fill the glasses ¾-full. Top with club soda and a few cranberries for garnish. Add a sprig of rosemary to use as a stirrer.

Step 5

To make a large batch: Pour vodka, lemon juice, and simple syrup into a pitcher filled with ice and stir well to combine.

Step 7

When ready to serve, pour the drink mix into an ice-filled rocks glass to ¾-full. Top each drink with club soda and a few cranberries for garnish. Add a sprig of rosemary to each drink as they are served to use as a stirrer.

Step 9

If you make the large batch before your guests arrive, be sure to keep the pitcher in the fridge to ensure the drinks are icy cold when they arrive.
