The Crimson Slippers Cocktail taught me that rum and Campari are an astonishing, and nearly perfect, combination. Just make sure it doesn't get too sweet.
The Vermouth Trilby Cocktail: dry vermouth, Cointreau and bitters, with a whiskey float.
The Chrysanthemum Cocktail: dry vermouth, Bénédictine and absinthe. Gorgeously balanced and, with an orange twist, has a delightful nose.
