Falernum and the One Eyed Willie

A few weeks ago my friends Mike and Charisse brought Charisse's sister to Psycho Suzi's for a drink. The sister ordered the Coconaut (which I love) and Charisse got the One Eyed Willie (which I've never had). With my curiosity raised, I decided to give the cocktail a try in the near future. 

One of the ingredients for the One Eyed Willie is falernum which I've never heard of. According to Wikipedia: 

"Falernum (pronounced fal-learn-um) is a sweet syrup used in Caribbean and tropical drinks. It contains flavors of almond, ginger and/or cloves, and lime, and sometimes vanilla or allspice. It is used in cocktails in a manner similar to orgeat syrup or can be drunk on the rocks."

"The syrup from can be alcoholic or nonalcoholic."

"The consistency is thick, the color can be white to light amber, and it may be clear or translucent."

"Some reports have the origination of falernum dated back to the 18th century."

In the literary magazine All the Year Round, owned by Charles Dickens, Jr. at the time, an unnamed author wrote of falernum in 1892, describing it as 'a curious liqueur composed from rum and lime juice.'"

Another drink in which it is used it the Zombie.
