Layer the two spirits in the shot glass, with the high-proof liquor on top. Light the shot and allow it to burn; then extinguish it by dropping it into the beer glass. Drink immediately.
A Flaming Doctor Pepper is a flaming cocktail said to taste like the soft drink Dr Pepper, although Dr Pepper is not one of its ingredients. It is usually made by filling a shot glass with 3 parts Amaretto and 1 part high-proof liquor, such as Everclear or Bacardi 151. The two liquors are not mixed; the high-proof alcohol is layered on top of the Amaretto. The shot is then set on fire and dropped into a glass half-filled with beer. The flames are extinguished by the beer, and the cocktail should then be drunk quickly.
