Flips were originally hot drinks made with egg and a variety of liquors and wines. They were warmed up by means of a loggerhead, an iron tool with a long handle and bulbous end that could be heated and plunged, like a poker, into the drink. Today, however, flips are generally served cold. Historically, they have been most often served in the morning or at bedtime, because of their soothing character.
Preparation Combine all ingredients except the nutmeg in a cocktail shaker and shake vigorously. Strain into a 5-ounce stemmed glass, and grate a little nutmeg on top.
