I'll start: I took a Russian cooking class at my college a couple of years ago, and we made our own infused vodkas. (None of this was paid for with departmental money -- a lot of us were underage!) The weirdest of these was garlic-infused vodka. No one would drink it but me -- I loved it!
How about you? What's the weirdest alcohol you've ever had, or weirdest drink you've ever mixed?
