Have you ever heard of fassionola ? It was invented around 1930 and used in Tiki drinks of the time. It has been suggested that Donn Beach (Don the Beachcomber) created it, but no documentation has supported that. The only other source of this mythical syrup was the Jonathan English Company, now closed. Based on older bottles of fassionola that have been located and tasted, it is said that the taste is similar to that of a passion fruit syrup. With the resurgence of Tiki drinks in the last few years and attempts to obtain original recipes, most bartenders will create their own version of fassionola. So, the next time you are making a Cobra's Fang, remember you may get close to the original recipe but there will always be that missing original fassionola component.
