Dirty Banana

I want to say that this is health food because it has a banana in it, well hum, I don't know but is sure sounds delicious!  I am trying this one soon.

1 medium banana frozen
2 oz dark rum
1/2 fl oz tia maria
2 fl. oz half and half
ground allspice

Put peeled banana in a blender along with rum and tia maria, add the half & half and blend until smooth. Pour in chilled wine glass, garnish with allspice. Sounds a little like Brown cow but with banana added, cheers!
