Manhatten, a simple to mix American cocktail. Two jiggers of bourbon whiskey, a jigger of sweet red vermouth, a couple of Marachino cherries, four dashes of Angostura bitters. Use a short glass, mix the booze in the glass, and add all the ice that will fit. Very smooth, and you don't want to mix a second one of these.
Goes good with pork ribs.
