Martha's Manhattan

Made with just three ingredients, the Manhattan is an easy drink to commit to memory. You'll need American whiskey, sweet vermouth, Angostura bitters, and a maraschino cherry for garnish—that's it. The only controversy is the whiskey: Some say it must be bourbon, while others vehemently call for rye. Martha says either works, so use your favorite when making her rendition of this classic cocktail. A good-quality cherry for garnish is also key, Martha explains.
