Combine all simple syrup ingredients in a small saucepan and bring up to a simmer (but do not boil). Once the sugar has completely dissolved, turn off the heat and let steep for at least one hour. Strain, then store in a jar or squeeze bottle and chill until needed.Muddle the clementine in the bottom of a cocktail shaker. Add ice, vodka, simple syrup, and cranberry juice, then give it a good shake. Strain into a glass filled with ice, then top with Reed’s REAL ginger ale. Garnish with a rosemary sprig and a few fresh cranberries.
