Pupusas - also known as pupisio - were first created by the Pipil in El Salvador. Over time cooking material for their preparation have been found in Joya de Cerén, “El Salvador’s Pompeii”, place of a native small town that was buried by ashes from a volcano explosion, and where foodstuffs were preserved as they were being cooked almost two thousand years ago by the tribes. The articles for their preparation have also been found in other archaeological sites in El Salvador.
