Cheers! A crisp gin drink is a delightful thing, and these recipes present a tempting variety of cocktails, from the classic to the exotic, from coolers and fizzers to high spirits. Of course, there's a basic Dry Martini, but there's also a version from New Orleans with Pernod. The Opera glints golden with gin, Dubonnet, and Curacao. Travel to Paradise on a combination of gin, apricot brandy, fresh orange juice, and a dash of lemon juice. Mix up a John Collins or Lime Gin Fizz. If you dare, go for the Knockout: it includes vermouth, Creme de Menthe, and Pernod with the gin, and it's strong stuff. Plus: the Luigi, which looks like a beautiful sunset; the Burnisides; and the Red Kiss.
