Known as tlaxcalli in ancient times, it has been a staple food in ancient Mexico since 3,500 years ago. Tortillas are still a must in almost every Mexican family meal, dipped in sauces or to make tacos. The nixtamalization process that tortillas go through significantly enriches the nutritional value of maize as a source of vitamins, minerals (calcium) and protein. They can be fried to make tortilla chips to prepare chilaquiles with sauce or just to be dipped in cheese, guacamole or a sauce of your preference.
