Henry, the guide for our 3-day hike around Sucre, was originally from Potosí. We told him that we had plans to visit his hometown, and he enthusiastically rattled off a number of recommendations. Churches, neighborhoods, shops... "But no matter what", he said, suddenly turning serious, "make sure to get a bowl of k'alaphurka". We were speaking Spanish, and I'd had a few beers. I could have sworn he said Cara Puta. "Really, Henry? You want me to go into a restaurant and order a steaming hot bowl of "Whore's Face"?!"
