Tom and Jerry is a classic American holiday cocktail that is traditionally consumed during the festive Christmas season. It is made with a combination of egg yolks, egg whites, sugar, brandy, rum, butter, milk, and warming spices such as cinnamon, cloves, and nutmeg.
In order to prepare it, the frothy egg batter is mixed with brandy and rum, and the combination is then topped with milk and nutmeg. The cocktail is typically served hot in a mug. It is believed that Tom and Jerry was invented in the 19th century by either "Professor" Jerry Thomas, the father of modern mixology, or Pierce Egan, a British journalist.
