A tortilla (/tɔːrˈtiːə/, Spanish: [toɾˈtiʎa]) is a typical food, circular and flat, typically made from nixtamalized corn or wheat flour. The Aztecs and other Nahuatl speakers call tortillas tlaxcalli ([t͡ɬaʃˈkalli]). First made by the indigenous peoples of Mesoamerica before European contact, tortillas are a fundamental part of many countries of the American continent. The origin of the corn tortilla in Mesoamerica dates back to before 500 BC. For example, evidence shows the peoples of the Oaxaca region in Mexico made tortillas at the end of the Villa Stage (1500 to 500 BC).
