Refreshing and delicious! The flavors balance beautifully. I used Doorly's Barbados rum, rich Cuban espresso, Licor 43, and my own coffee/chocolate bitters. The spiced, vanilla flavors compliment the espresso and rum without being especially sweet and the coffee is solid without over powering. This is a memorable alternative to our favorite espresso martini. Definitely will be on our regular holiday afternoon repertoire.
