Eggnog, also known as egg nog, is a sweetened dairy-based beverage made with milk and/or cream, sugar and beaten eggs (which gives it a frothy texture), and flavoured with ground cinnamon and nutmeg. Various liquors, such as brandy, rum, whisky, advocaat and/or liqueurs, are often added.
Eggnog is a popular drink throughout the United States and Canada, and is usually associated with winter celebrations such as Christmas and New Year. Commercial non-alcoholic eggnog is typically available only in the winter season. Eggnog may be added as a flavouring to food or drinks such as coffee and tea. Eggnog-flavoured ice cream is a seasonal product in the United States and Canada; as eggnog is a custard it can be easily repurposed as an ice cream base.
