perfecting the Dirty Banana

Since being back from the Caribbean I have been missing the killer bevy of blended cocktails that we enjoyed so I figured there was only one logical thing to do. My loyal Osterizer blender was promptly taken out of retirement and given front and center status on the kitchen counter. One of my first challenges was the Dirty Banana. Thanks to some cross referencing of internet recipes and a few ripe bananas on the shelf I came pretty damn close. This one was good enough to photograph. To answer my friend Greg's question, and for anyone else that might be interested, this is all you need:
1 oz. dark rum
1 oz. Kahlua
2 oz. milk
1 ripe banana
4-5 regular sized ice cubes

Blend for one minute.

Heavenly.
