Charles A. Tuck came up with this winner in 1937 to honor of the 20th Century Limited train running between New York City and Chicago. The chocolate should just be an undertone in this one, not the star. Adjust the amount of crème de cacao to your taste. 1 1/2 ounce gin 3/4 ounce Lillet Blanc 1/2 ounce white crème de cacao 3/4 ounce lemon juice Place all of the components in a cocktail shaker and shake vigorously. Pour into a cocktail class and garnish with a lemon twist (optional).
