- Layer the ingredients in a shot glass: start with Kahlua, followed by Baileys, then top with Sambuca.
- Prepare a small, heat-resistant glass with vodka or rum in it as the base.
- Carefully light the Sambuca on fire using a long lighter or match.
- Once lit, carefully drop the shot glass into the base glass without extinguishing the flame.
- Drink quickly while it’s still flaming.
