More commonly spelled pacharán, from Navarre (home of Pamplona and a lot of good wine country) and the Basque Country. It's great stuff, like a sloe-berry infused anise liqueur, a superb, slightly sweet cordial. I've been looking for it in the US for a while without much luck. I'm personally fond of the Basarana brand, which I first found at the bar at Biba, a now-bygone Boston restaurant. I was lucky to bring some home recently from Mexico, a popular brand called Zoco, which is a bit meeker, paler, and less interesting than Basarana, but beggars can't be choosers.
