Ok, this surprised me...wait, scratch that, this one shocked me! Coffee, sugar, eggs & lemon...almost breakfast, huh? Nah, much more. Much, much more.
2.5 oz Kahlua
1 oz freshly squeezed lemon juice
0.5 oz simple sugar
1 egg white
Lemon twist (garnish)
Cinnamon (optional garnish)
Pour Kahlua, lemon juice, simple sugar & egg white into a shaker. Dry shake for 10-15 seconds. Add a bunch of ice to the shaker and shake again, harder and longer. Strain into a martini or rocks glass...or maybe even a coffee mug.
