Yesterday evening, while relaxing after dinner, we heard an eerie, extremely loud, and other-worldly howling whistle in the street that we had never heard before, more like an alien invasion than the knife grinder’s melodious occarina like sound, or the Basura’s metal clanging. Rushing outside we discovered it was a Camotero alerting his presence, and pushing this amazing machine, like a tiny locomotive with a five foot chimney, a blazing firebox below, and a tray of steaming camotes (sweet potatoes) above. The camotes are chopped and sprinkled with sweetened condensed milk and cinnamon, and after handing over twenty pesos we discovered are also delicious.
