Fassionola is a typically fruit-flavored (passion fruit and others), red-colored syrup that was frequently used in tropical drinks during the 1930s but is now a relatively unusual ingredient.
[7] Claimed to have been first fashioned in 1916,[8] the complete history of fassionola is unclear but is closely associated with Donn Beach (AKA Don the Beachcomber).
Beach cites his childhood as growing up near New Orleans, and he sometimes used fassionola in making what came to be known as "tiki drinks" in his 1930s-era bars.
Trader Vic listed what he called "passionola" in the index of his 1972 revised Bartender's Guide.
[12] He described it as "a non-alcoholic syrup made from passion fruit [that] comes in three colors — red, green, and natural".
