1/2 a fluid ounce or 1.5 centilitres of Sambuca
1/2 a fluid ounce or 1.5 centilitres of Creme de Menthe

Pour the Sambuca into a shot glass, and light it. You should see a small blue flame. Quickly place your palm over the glass. You should feel the suction (it will put the flame out). Remove your hand and mix the creme de menthe with the Sambuca when it is not on fire and drink. ALWAYS USE CAUTION WITH FIRE.
