My friend just came up with this awesome impromptu cocktail:

"Approximate spec for that spiced drink (I didn't do actual measurements): 1 oz Kraken spiced dark rum, 1/2 oz Mount Gay Barbados rum, 1/2 oz velvet falernum, 1/3 oz lime juice, 2-3 oz sparkling orange juice, garnish with sprinkle of cinnamon"
