A festive-looking and also tasty cocktail for the holidays is the Green Vesper. It’s a gin & vodka martini with absinthe instead of vermouth, and without the olive which really wouldn’t go with the licorice taste of the absinthe.
Three measures of gin, one measure of vodka, half a measure of absinthe. Shake in cocktail shaker until ice cold, strain into martini glass. Optional garnish is a peel of lime. Drink until jolliness and gaiety set in, which shouldn’t be long.
