The Lounge Lizard is a nice and easy mixed drink that can help you break out of a routine. If you enjoy a good Rum & Coke, then you should certainly give this one a try.
It's quite simple: the Lounge Lizard is nothing more than a shot of dark rum, quarter shot of amaretto, and cola. It is the rum switch and liqueur addition that make it a little more interesting and, though the changes are subtle, it's also quite nice.
While Coke (or Pepsi) may be your first cola of choice, try to remain open to using some of the lesser-known colas. RC Cola works great here, though a wonderful brand is Q Kola, which is unlike any 'cola' many of us are used to. It was made specifically for mixed drinks and has a lighter taste that really allows the other ingredients to shine through.
