My first reaction was yuck, but then I thought about the sassafras leaves I used to eat as a child. Sassafras root is used in root beer, and it has a sort of unique sweet flavor. It makes me think of ginger snaps, another biscuit flavored with a root.
My grandmother used to make sauerbrauten (sour beef-a sweet & sour German dish) by marinating the beef in vinegar and pickling spices then cooking them in a broth flavored with gingersnaps.
Cookies are easy and cheap to make yourself and the results are usually far preferable to storebought versions. I've got a great recipe for gingersnaps if you are interested.
