Corn tortilla in the context of "Masa harina"

A tortilla (/tɔːrˈtiːə/, Spanish: [toɾˈtiʝa]) is a thin, circular unleavened flatbread from Mesoamerica originally made from masa, and now also from wheat flour.

The Aztecs and other Nahuatl speakers called tortillas tlaxcalli ([t͡ɬaʃˈkalli]). First made by the indigenous peoples of Mesoamerica before colonization, tortillas are a cornerstone of Mesoamerican cuisine. Corn tortillas in Mesoamerica are known from as early as 500 BCE. Flour tortillas were invented once the Spanish introduced wheat to Mexico in the 16th century.

Masa or masa de maíz (English: /ˈmɑːsə/; Spanish pronunciation: [ˈmasa]) is a dough made from ground nixtamalized maize. It is used for making corn tortillas, gorditas, tamales, pupusas, and many other Latin American dishes.

It is dried and powdered into a flour form called harina de maíz or masa harina. Masa is reconstituted by mixing with water before using it in cooking. In Spanish, masa harina translates simply to 'dough flour', and can refer to many other types of dough.

Birria (Spanish: [ˈbirja] ) is a regional variation of barbacoa from western Mexico, mainly made with goat, beef or lamb. The meat is marinated in an adobo made of vinegar, dried chiles, garlic, and herbs and spices (including cumin, bay leaves, and thyme) before being cooked in a broth (Spanish: consomé). Originally, birria was the regional name given in the state of Jalisco and surrounding areas to meats cooked or roasted in a pit or earth oven, what is known as barbacoa in other regions of Mexico, but for many people today, mostly in the United States, birria is now a distinct dish.

It is often served at celebratory occasions such as weddings, baptisms and during holidays such as Christmas and Easter, and even at funerals. Preparation techniques vary, but the dish is often served with corn tortillas, onions, cilantro, and lime. Birria is also served with tacos.

A tortilla chip is a snack food made from corn tortilla, which are cut into triangles and then fried or baked (alternatively they may be discs pressed out of corn masa then fried or baked). Corn tortillas are made of nixtamalized corn, vegetable oil, salt and water. Although first mass-produced commercially in the U.S. in Los Angeles in the late 1940s, tortilla chips grew out of Mexican cuisine, where similar items were well known, such as totopos and tostadas.

Though usually made of yellow corn, they can also be made of white, blue, or red corn. Tortilla chips intended to be dipped are typically only lightly salted, while others may be seasoned with a variety of flavors. Tortilla chips may be served as a garnish for soups or dishes such as chili con carne.

A taco (US: /ˈtɑːkoʊ/, UK: /ˈtækoʊ/, Spanish: [ˈtako]) is a traditional Mexican dish consisting of a small hand-sized corn- or wheat-based tortilla topped with a filling. The tortilla is then folded around the filling and eaten by hand. A taco can be made with a variety of fillings, including beef, pork, chicken, seafood, beans, vegetables, and cheese, and garnished with various condiments, such as salsa, guacamole, or sour cream, and vegetables, such as lettuce, coriander, onion, tomatoes, and chiles. Tacos are a common form of antojitos, or Mexican street food, which have spread around the world.

Tacos can be contrasted with similar foods such as burritos, which are often much larger and rolled rather than folded; taquitos, which are rolled and fried; or chalupas/tostadas, in which the tortilla is fried before filling.
