Brew up a pot of coffee using your favorite method.
If you want to a a sugar or caramelized sugar rim, now is the time. There are a few ways to do this:1) Pour a thin layer of sugar on a saucer. and a thin layer of simple syrup next to the sugar.2) Roll the rim of the glass around in the simple syrup and then in the sugar.
If you want to caramelize the sugar you can use a kitchen torch or a lighter. With either way you need to be careful that you don't get burned or break your glass.1) If using a lighter, you should roll a tiny amount of 151 around on the edge of the glass and then light that on fire to caramelize the sugar. This is a little less controlled than the torch method.2) To use the kitchen torch, simply apply the fire to the sugar and go around the rim while it caramelizes.
Measure 1.5 oz of Kahlua with the jigger and toss into the glass.
Measure .5 oz of triple sec with the jigger and toss into the glass.
Measure .5 oz of 151 rum with the jigger and toss into the glass.
Measure 4 - 5 oz of coffee with the jigger and toss into the glass. Or, you can just pour the coffee directly in the glass to top if off.
If desired, you can add a large dollop of whipped cream on top.
