I was just thinking along these lines... does anyone have a recipe for something like Herbsaint? If I am not mistaken, that is a absinthe substitue sans wormwood. I have had homemade anisette, and I wonder if it could be similar with less (or no) sugar. If the process is entirely different, I guess that would end my inquiry.
EDIT: I might be thinking of Pernod. Either one would be interesting to make. An anise liqueur which is not sweet, to my understanding.
