Fassionola: Fassionola is a typically red colored syrup that is fruit flavored (passion fruit and others) that was more frequently used in tropical drinks during the 1930s but is now a relatively unusual ingredient. It also comes in green and gold varieties that sometimes are made to taste differently. It is used as a fruit punch concentrate and some claim that a red colored fruit syrup called fassionola was an ingredient in the original Hurricane cocktail. Although a frequent attribution, solid evidence of fassionola's use in the Hurricane from before 1956 is currently lacking, and it is not known what were the precise ingredients in the earliest version of fassionola.
Falernum: Falernum is either an 11% ABV syrup liqueur or a nonalcoholic syrup from the Caribbean. It is best known for its use in tropical drinks. It contains flavors of ginger, lime, and almond, and frequently cloves or allspice. It may be thought of as a spicier version of orgeat syrup. The form can be alcoholic (syrup liqueur) or nonalcoholic (syrup). Versions with alcohol are generally lower in proof (≅15 ABV), adding rum and emphasizing the clove, ginger, or allspice flavoring aspects for use in mixing cocktails, typically tropical or tiki drinks. It is also enjoyed on the rocks. Depending on sugar content, the consistency is often thick and is therefore sometimes referred to as "velvet falernum" because of the feeling it leaves on one's tongue. Brands vary and the color can be white to light amber, and it may be clear or translucent.
