The Manhattan formula, so simple but so adaptable, gives rise to endless variation. Some of these are deliberate attempt to rearrange the basic mixture; others seem to have arisen from the simple fact that a combination of a spirit, vermouth & bitters is a mighty fine one and a solid foundation for a very good drink.
One of these variations is the Palmetto, recorded in the Savoy Cocktail book. This puts the drink in the period between the publication of the book and the repeal of Prohibition, making it one of the cocktail ‘classics’. Harry Craddock’s recipe combines rum, vermouth and bitters & is faithfully recreated in Robert Simonson’s excellent book, 3 Ingredient Cocktails; I used his recipe here. One of the key things to note is that bitters here are very important – both rum and the Italian vermouth are quite sweet, so the citrus kick of the bitters is necessary to tie them together, but add too much & they will overpower the drink.
I’m not enamoured with this drink; the equal mix of vermouth and rum just doesn’t seem to work together for me, even with a good shake of bitters; somehow it’s just all too sweet. But it is a complex drink and worth trying, even just once.
1 1/2 oz good, aged rum
1 1/2 oz sweet vermouth
Dashes of orange bitters
Stir over ice, then strain into a chilled coupe. Garnish really seems to be optional for this drink, but a good slice of orange zest wouldn’t go amiss; if you use a cocktail cherry, you would be adding to the sweetness even further.
