Nutmeg is a warm, aromatic spice derived from the seeds of the nutmeg tree. It is commonly used in powdered form and is known for its sweet yet slightly spicy flavor. In the context of alcohol and cocktails, nutmeg is primarily used as a garnish or a flavoring component. It adds a rich, warming touch to a variety of drinks, especially those that are creamy or have a base of dark spirits like rum, brandy, or bourbon. Nutmeg is a key ingredient in classic cocktails such as the Eggnog, Brandy Alexander, and the Painkiller, where it complements the other flavors and adds a festive, aromatic finish. A light grating of nutmeg on top of a cocktail can enhance its aroma, making it a popular choice for holiday and winter drinks.
