This sweet, sophisticated tropical treat is an ideal cocktail for spring evening gatherings. In a tall 8 ounce glass, begin with 1.5 ounces of Papagayo Organic Spiced Rum over ice. Add 2 ounces of guava nectar (available from natural food stores and specialty grocers) and stir. Top off with cream soda while gently stirring, creating a light froth. Garnish with a dash of ground cinnamon.
