I was at a party lastnight and someone had Patron Coffie there, never having it before I saw that it had a much higher proof than Kaluah. I substituted Kaluah for it in a B-52 to make it much more stronger. I assume that you could also find a orange liqueur with a higher proof also to make this even more effective.
1/3 Patron Coffie
1/3 Grand Marnier
