1 bottle of 80 proof vodka (I do not think it has to be the really good stuff)
12 vanilla beans
Remove approximately 1/4 cup of the vodka from the bottle. With a sharp knife (I used a sharp cleaver) slice the vanilla beans lengthwise. Add the the vodka in the bottle. Shake and put in a cool dark place for approximately 2 to 3 months. The instructions indicate that we should shake the bottle at least once a week.
All this extract will surely come in handy for cookie making season...i.e. Christmas!
