The long cold nights are drawing in and party season is upon us. And what better way to celebrate having found the perfect party LBD (if you haven't, fear not, we've got some great pieces here), than with the festive and fruity Christmapolitan. This cocktail is a classic Cosmopolitan with a seasonal twist of Amaretto and has been designed for Little Black Dress by the UK's leading mixologist Simon Difford of www.diffordsguide.com. Simon promises that this contemporary cocktail is quick and easy to make, and the perfect drink to serve at a Christmas party. Team LBD are sold! How to make your Christmapolitan: 1 ½ shots* Vodka 1 ½ shots Cranberry juice ½ shot Amaretto ½ shot Freshly squeezed lime juice * 1 shot = 30ml Method: Simply pour all of the ingredients and a handful of ice into the cocktail shaker to the top. Shake vigorously for 15 seconds so that you get enough dilution from the ice and strain into a Martini glass. Garnish with a string of redcurrants and serve. Simon says: "If you can’t get hold of redcurrants to finish this cocktail, any festive garnish will do – it’s your chance to be creative. Why not decorate it with a candy cane or a sprig of holly?"
