Blue Blazer

A flaming drink is a cocktail or other mixed drink that contains flammable, high-proof alcohol, which is ignited before consumption. The alcohol may be an integral part of the drink, or it may be floated as a thin layer across the top of the drink. The flames are mostly for dramatic flair. However, in combination with certain ingredients, the flavor of the drink is altered. Some flavors are enhanced, and the process may impart a toasted flavor to some drinks. While alcohol has historically been both consumed as a drink and used as fuel for fire, the first instance of a flaming alcoholic drink is uncertain. [citation needed]
