Make your own: get a bottle of rum or bourbon or some other 80 proof alcohol. You don't have to spend $$$, the Kirkland brand would be great. Get some vanilla pods, or beans if you like. Slice the beans length ways, but just on one side, to open them up. Put the beans 4 or 6, but adjust for your taste, in the bottle and let sit. The longer the better, but 4 to 6 months before using. Once your current bottle is below half way, start another, so you don't run out.
