First add 1 part tequila to the shot glass. Then add the sambuca and a few drops of tabasco sauce. Instead of tabasco sauce you can add 2 to 3 coffee beans instead (try one of each and see what you like better). Pour some sambuca all over the glass and light it on fire. Let it burn for approx. 10 to 20 seconds. You can now leave it burn and sip through straw or blow out (carefully) and take it down like a normal shot. Don't forget to eat the beans. Have fun!
