Sort of off-topic, but I heard an interesting story of why caldo maragato was served differently to the caldo gallego further west, and other versions of caldo. Because the Maragatos (the folk around Rabanal, Astorga etc) were itinerant traders, they ate their broth last as a way of keeping the meat and veg warm for longer. I'm told that's still the tradition, but it wouldn't surprise me if others timed the serving of the broth in much the same way. I ended up having a late breakfast with Pilar and her daughter in Rabanal and they told me much about the region, but I neglected to inquire more about the caldo since it hadn't been on the menu the night before.
I'm glad someone else finds all this interesting, Kellyz. Maybe others will know more.
