Method:Rim martini glass with sugar mix.
Shake rum, amaretto and sou mix with ice. Strain into glass and serve.
Fresh Sour Mix - combine 1 tablespoon of each sugar, water, lemon & lime juices.
Notes:"It was as dark as a motive, and smoky on the tongue, like a kiss between cigarettes. It didn't even have a name. There was sugar on the rim, but wait, there was an adult spice in the sugar, too - a coarse powder of freshly ground cinnamon. I felt as if the drink was watching me, sleepy-eyed, to see if it was working"
