HERE'S WHAT YOU NEED:
2 parts coffee {old & cold preferably}
1 part sweetened condensed milk
1 part Myer's Dark Rum
your Martini shaker
a pretty Martini glass
some pretty sugar for the rim
3 coffee beans for good luck
HERE'S WHAT YOU DO:
fill your shaker with ice, add the coffee, "milk" and rum. Shake, shake, shake and then shake a little more.
Dampen the rim of the glass and gently roll in the sugar, strain the "martini" into glass, add 3 coffee beans, take pictures of it all over your house... oh wait, that's just me.
You should sit back and prepare to smile. It's lovely.
