eggnog, a drink thought to have originated in the British Isles, composed of beaten eggs, sugar, and cream or milk and typically served during the Christmas and New Year’s holidays. A sort of liquid custard, eggnog often contains a small quantity of liquor as well, with rum, brandy, cognac, and whisky being among the typical alcoholic amendments.
A word derived from Scottish and Irish Gaelic, a noggin is a cup; by extension, in early modern English, it came to mean a small quantity of alcohol, a quarter of a pint or less. Both senses are applicable to eggnog, a traditional holiday drink. It was thought that the use of “luxury” ingredients such as cream and alcohol would invite prosperity into the household for the coming year. In most households today, a cup of eggnog ushers in the good cheer of the holiday more so than any belief in impending wealth.
The origin of the drink was likely a monastic holiday beverage called posset, made of milk and eggs and usually laced with ale, wine, or barleywine. It is first attested in medieval England in the 14th century. Although the treat originated in Britain, the term eggnog first appeared in Britain’s North American colonies—soon to be the United States—in 1775. George Washington served the drink during the Christmas holidays to family and guests at his home in Mount Vernon, Virginia, with his recipe calling for a staggering tablespoon of sugar for every egg. Eggnog had become widespread during that season by the time cadets at the United States Military Academy rioted on Christmas Eve and Christmas Day, 1826, over regulations that prohibited them from consuming alcohol on campus; in the aftermath, 11 cadets were expelled.
The early popularity of eggnog in the United States can probably be explained by the fact that all of its constituent ingredients were relatively more abundant and less expensive than in the British Isles, but today it is popular throughout the English-speaking world. Eggnog is usually served at room temperature, but in Australia and New Zealand, where Christmas falls at the beginning of summer, it is chilled.
