You know, I bet if you took some good cheap rye like Old Overholt or something and put a few caraway seeds in for maybe a week, it'd pass without a murmur.
Oh my god nøkkelost akavit I just thought of it! Whole cloves and untoasted cumin seeds.
In parts of Scadanavia due to taxes lots of people import via ferry duty-free stuff from abroad or make their own moonshine-style booze or make their own flavoring for the stuff. The Salmiakki licorice for example steeped in cheap vodka is something the kids do (not kids, but, high school/college) I'm told. I think Iceland actually sells a commercial produce. Think a Jagermeister-like flavor but with more salt, aluminum chloride salt, not table salt. An acquired taste.
