Frozen Mango Daiquiri

Pour the rum into a glass, add the mint and muddle together using a muddler or the handle of a wooden spoon. Strain the rum (to remove the mint leaves) then pour into a blender. Note that you can add the mint to the blender if you prefer, but the final drink will take on a greenish tint instead of bright orange. Add the lime juice, mango and simple syrup to the blender and fill with ice. Puree until all the ice is broken up. Pour into chilled margarita/daiquiri glasses and garnish with a sprig of mint.
