Make the Simple Syrup

1. Combine the water, sugar, rosemary sprigs and clementine peels in a small saucepan and bring up to a simmer over medium-low heat (do not boil).
2. Once the sugar has completely dissolved, turn off the heat and let steep for at least one hour or until cool.
3. Strain out the solids, then store in a jar or squeeze bottle and chill until needed. Makes 1 1/2 cups (12 ounces) and can be made up to 5 days in advance.

Make a single cocktail

1. Muddle the clementine and rosemary in the bottom of a cocktail shaker.
2. Add vodka, simple syrup, cranberry juice and ice, then give it a good shake.
3. Add ice to a glass, then strain the mixture over top leaving about 1 inch of room. Top with club soda or sparkling wine.
4. Garnish with a rosemary sprig and a few fresh cranberries if desired and serve immediately.

Make a pitcher (serves 16)

1. Muddle the clementines and rosemary in the bottom of a pitcher. Alternatively you can muddle the fruit in batches in a cocktail shaker or pint glass and then add it to the pitcher.
2. Add vodka, simple syrup and cranberry juice, then stir until well combined. Let sit for 1 hour to infuse.
3.  Strain to remove the solids, being sure to press and squeeze out as much liquid as possible. Pour the liquid back into the pitcher and refrigerate until ready to serve. Can be made up to one day in advance.
4. Pour into glasses with ice, leaving about 1 inch of room on top. Pour club soda or sparkling wine over top.
5. Garnish with a rosemary sprig and a few fresh cranberries if desired and serve immediately.
