Garbure
This is the cassouletlike dish of the mountains between Spain and France, claimed by several cultures. When I was there, I was told that each of twenty different versions was the “only” authentic one; in this way, too, it’s like cassoulet. What they all had in common were the large white beans called Tarbais (after Tarbes, one of the larger towns of the region)—which you probably will not be able to find—and a stultifying heartiness. Great stuff: you must serve it with crusty country bread and a good red wine.
