Lucien Gaudin was a French fencer who won gold medals at the '24 and '28 Olympic Games. So fond were the French of this master swordsman that they named a cocktail after him after his most recent victories. His namesake is one with a very European flare with its use of gin, vermouth, Cointreau and Campari. Delicious!
Garnish: lemon twist.
Stir with ice. Strain into a cocktail glass.
