A 1920s cocktail book lists this as a South American favorite. That’s quite possible, though I suspect its popularity was limited to those South Americans who wore London suits and Paris frocks and spent their days at the Club, not the ones who actually worked for a living. A very fine cocktail, nonetheless. One thing: don’t use green Chartreuse instead of yellow; the results are unpleasing to the palate.
2 ounces gin, London dry gin, Plymouth gin or for true madness, Old Tom gin
1 ounce red vermouth
1 teaspoon yellow Chartreuse
To finish: lemon peel
Stir and strain into a chilled cocktail glass; twist lemon peel over the top.
