Carrington i Fraser, 2003, p.74, A liqueur made basically from rum, lime and sugar. The origin of the name is something of a mystery. The authoritative Grossman's Guide states falernum was invented in Barbados over 200 years ago and was named after Falernum wine, which was much prized by the Romans. There is a joke which purports to explain how falernum got its name. In one version, the tourist, after tasting the drink, ask the old man how he made this delicious liqueur. After a few moments hesitation the old Barbadian replies 'you have fuh learn um' (you have to learn it). The following is reproduced from Mrs. H Graham Yearwoods's (1911) West Indian and Other Recipes: 'For 30 gallons of falernum: 9 gal. rum, 3 gal. lime juice, 1 gal. milk, ½ gal brandy, 56 lbs. sugar, ½ oz. bitter almond, ¼ oz. mace. To fine it, add 1 gal. of milk.' Rum and falernum constitute the drink known as Corn 'n Oil or 'Corning Oil'. The traditional rum cocktail is simply rum and sugar of rum and falernum shaken with ice and a dash of Angostura Aromatic Bitter.. Carrington, Sean;Fraser, Henry.«Falernum».
