Fill a mason jar up with 6 ounces of your favorite gin and 2 sprigs of rosemary. Let this sit over night to flavor the alcohol. Meanwhile, freeze 2 martini glasses in the freezer for about an hour. Drizzle chocolate syrup around the inside of the martini glass and put it back in the freezer until ready to use. Remove the rosemary sprigs from the gin and set aside to use for your wreath. Add the gin and cherry juice to a shaker full of ice and shake for a full 60 seconds. Pour it into the chocolate drizzled martini glasses and garnish each martini with a cherry wreath.
To make the wreath
Skewer 2 cherries with the end of the rosemary sprig. Put a toothpick through the other end of the cherries and wrap the loose end of the rosemary around to make a wreath shape.
