Kahlua under the Sink

I always thought of this as my father's recipe, but according to the card, my mother's cousin Averil Jean wrote it out when she was visiting in May 1969. This recipe is part of family legend. Can't say I recommend the result.

Boil water.
Mix sugar and coffee.
Add boiling water.
Cool; add brandy. Pour into a half-gallon glass wine bottle.
