2 tsp Grenadine (1/3 oz)
2 dash Maraschino (1/6 oz Luxardo)
2 dash Angostura Bitters
Stir with ice and strain into a cocktail glass. A recipe in another Trader Vic book included a lemon twist (but I saw that recipe afterwards and thus did not have a garnish here).
Two Tuesdays ago, I reached for Trader Vic's 1981 edition of the 1946 Book of Food & Drink and spotted the Canton that was listed as a Trader Vic original. The recipe read like a rum Old Fashioned with the sweetener being a combination of grenadine and Maraschino seen in other drinks of that era like the Mary Pickford and the Champs-De-Mars Daiquiri. After the drink was made, I later found the recipe in Trader Vic's 1947 Bartender's Guide, and it included a lemon twist.
