You won't find a simpler drink in the world than pouring three bottles into a bowl for a large-batch Negroni Sbagliato—a combination of Campari, sweet vermouth, and prosecco (which takes the place of the traditional gin). Jeffrey Morgenthaler, bar manager of Clyde Common in Portland, is known for barrel-aging cocktails and other fancy bartender tricks. But when he throws a party, he makes this easy, lightly bitter drink. Here's how: Chill one bottle each of Campari, Cinzano sweet vermouth, and good, inexpensive prosecco. Dump all three in a serving bowl with a hefty block of ice and serve with big ice cubes.
