Some recipes include alcohol, such as rum or bourbon, while others are non-alcoholic, making it suitable for all ages. This festive beverage is typically served chilled and is popular during the Christmas season in many countries. Eggnog can be enjoyed on its own or used as a base for various desserts and cocktails, making it a versatile addition to holiday celebrations.
