A hot, frothy holiday classic — a spiced, spirited cousin of eggnog. A spoonful of sweetened egg batter is loosened with brandy and dark rum, lengthened with hot milk, and crowned with grated nutmeg, leaving a meringue-light cap over a warm, custardy body. Its origins are contested: Jerry Thomas claimed it and spread it across 19th-century America in his Bar-Tender's Guide, though the drink predates him, with its name owed to Pierce Egan's 1821 London characters. Still a Midwestern winter ritual.
Garnish: Grated Nutmeg
