"For each glass, liberally large, the basic ingredients begin with ice cubes in a shaker and three or four drops of Angostura bitters on the ice cubes. Add several twisted lemon peels to the shaker, then a bottle-top of dry vermouth, a bottle-top of Scotch, and multiply the resultant liquid content by five with gin, preferably Bombay Sapphire. Add more gin if you think it is too bland... I have been told, but have no personal proof that it is true, that three of these taken in the course of an evening make it possible to fly from New York to Paris without an airplane."
