One of my most beloved cocktails, edified by the master bartenders of cozy Cafe Soriah to the afterhours set of restaurant workers and au fait locals in Eugene, Oregon during the mid-oughts.
There was a strange "game" surrounding the presentation of the drink (which I still don't quite understand), where the bartender would bring the shaker to you and strain the drink table-side, and if they failed to empty the entire shaker and fill the glass to the top (without spilling over), they would leave the shaker with remaining deliciousness for you to finish at your leisure. Only thing was... there was ALWAYS extra.. Like, often twice as much extra!
Funny.. no one ever complained, and welcomed this odd ritual with hoots and hollers!
1 shot espresso
1 1/2 oz tequila
1 1/2 oz Kahlua
1 oz Baileys
Shake over ice
Strain into a chilled martini glass
Enjoy the rush!
