Add the 1 oz of Kahlua and then add the 1 oz of Bacardi 151 rum to the shot glass. Place a small sipping straw in the mixture and then light on fire. The straw is so you do not burn your eyebrows off. Once lit suck the shot through the straw till empty. Tastes like chocolate milk. I have made this drink quite often at parties and it goes over very well with everyone. Try it a few times it does take a little practice to get it right.
