1) Fill a cocktail shaker or small pitcher with ice. Add the whiskey liqueur, pear nectar, Licor 43 and bitters. Cover and shake vigourously until thoroughly mixed and chilled, about 30 secs. (In general, the drink is ready by the time the shaker mists up.) Strain into a chilled cocktail glass. Garnish with the pear. Drink.
* Cook's note: Licor 43 is a sweet Spanish liquor made with 43 different herbs and spices. It has a pronounced vanilla flavour with a slight citrus note.
