This one comes from eGullet, and before that from bartender Jacques Bezuidenhout at Pesce restaurant in San Francisco.
In some ways this would be good drink for introducing people to Campari. OK, the dose of Campari is kind of heavy for that purpose. Still, the classic Campari drinks (i.e. the Negroni and the Americano) are complicated by the inclusion of vermouth – another problem ingredient for many people. This drink is free of vermouth, Grand Marnier increases the sweetness, and fruit juice lightens things a little. In fact the drink is purely about rich and bitter sweet citrus. The taste is intense but free of surprises. While quite bitter, this drink reflects the current fashion for drinks that are light on spirits and heavy on juices and liqueurs.
