Homemade vanilla extract with brandy

Cut the vanilla beans lengthwise. Pour the brandy into a clean bottle that you can seal well. (I use an old soy sauce bottle that has been washed on high heat in the dishwasher. These bottles come with a plastic stopper and a nice pouring type cap. A corked bottle would work well too.) Add the cut vanilla. Seal the bottle and let it sit for about 1 month. The extract will not go bad because of the brandy, and there is no need to refrigerate.
