3/4 oz Drambuie® Scotch whisky
3/4 oz Grand Marnier® orange liqueur

Pour both ingredients into a brandy snifter. Tilt glass and flame the liquor. When flamed cover it completely so no oxygen escapes (very important). You will feel a suction to the hand, pop your hand off, take the shot, and immediately cover the glass again so no oxygen escapes. Make a slight hole in between your index and thumb, and inhale as much as u can, and hold it. That is the Nitrous Oxide!
