Eggnog is a rich, creamy beverage traditionally made with eggs, milk, cream, sugar, and spices such as nutmeg and cinnamon. It is often associated with the holiday season and can be enjoyed on its own or used as an ingredient in various cocktails. The base of eggnog provides a smooth, velvety texture that pairs well with a variety of spirits, making it a versatile addition to festive drinks.

When used in cocktails, eggnog can be combined with different types of alcohol to enhance its flavor profile. Common choices include rum, bourbon, or brandy, each imparting its unique character to the drink. For example, bourbon (a type of whiskey) adds a warm, caramel-like depth, while rum (a type of distilled liquor made from sugarcane) brings a subtle sweetness and spiciness. Brandy (a distilled wine) offers a fruity, complex note that complements the creamy richness of the eggnog. These combinations create indulgent, comforting cocktails perfect for holiday celebrations.
