What is modern day eggnog?

Modern-day eggnog is a sweet, creamy beverage made with milk, cream, eggs, sugar, and spices such as nutmeg and cinnamon. It is often served during the holidays, particularly Christmas. Eggnog is believed to have originated in the 17th century in England, where it was originally called "posset" and was made with hot milk curdled with wine or ale. Over time, eggnog evolved to include eggs and sugar, and it became a popular drink in Europe and America. Today, eggnog is a seasonal favorite that is enjoyed by people of all ages.
