Tortilla de rescoldo

Tortilla de rescoldo or ember tortilla is a traditional Chilean and Northern Argentine[citation needed] flatbread, often unleavened, that was commonly prepared by rural travelers. It consists of a wheat-flour-based bread, traditionally baked in the coals of a campfire or fireplace. It is common street food in populated areas or along roadways and sold by palomitas . The bread dates Spanish colonizers, who used it as a travel ration similar to pan subcinerario. Vendors known as palomitas, typically women dressed all in white, sell the tortillas in train stations and other public areas, especially in Antihue and Laraquete.
