Wiseguy

1 1/2 oz Tuaca citrus liqueur
3/4 oz Bombay Sapphire gin
3/4 oz dry vermouth
1 dash Angostura bitters

Invented by H.B. Stone. It is suggested not to add the dash of bitters unless Bombay Sapphire or another vapor-infused gin is used, or the drink may be too harsh. The glass has a pleasant aroma even when emptied.Shake and strain into a chilled cocktail glass. Twist a slice of lemon rind above the drink and rub along the rim, but do not drop into the drink.
