1/2 oz absinthe herbal liqueur
1/2 oz Stroh® 80 rum

Pour the two ingredients together in a shot glass (approximately equal amounts, or whichever you would rather have most of). Turn a tall glass upside down, and place it over the shot glass. Have a straw at the ready. Lift the tall glass up slightly, and light the shot glass, before placing the glass back down again, making sure that as little of the fumes can escape as possible. Then inhale the fumes with your straw from the still upside down glass, finishing off by shooting the shot.
