Perfect Workplace Food
There are currently two stories that come to mind when the origin of the burrito is questioned. One is that early Mesoamericans used tortillas to wrap food, with fillings like chilies, mushrooms, avocados, and other vegetables. The other story begins with the Pueblo people in early Southwestern region of the United States. Their tortillas held beans and meat sauces which are much closer to the modern style burritos. Moving forward into the early 19th century, you still have two separate thoughts: Burrito's were created to store food by vaqueros (horse mounted livestock herder) or by the miners in Sonara, California for the same reason: they were easy to eat and then continue working.
The Origin of the Name "Burrito"
Juan Méndez was selling tacos from a stand in the Mexican state of Chihuahua. Allegedly, he used a donkey for transport and to keep the food warm, he would wrap his food in large flour tortillas. Dubbing the wrapped tacos as a Burrito or food of the little donkey, Méndez soon found out that the name had stuck. The date of this popular folklore legend has been lost in time.
The Birth of the Mission Burrito
The type of burrito known to most Americans originated in the Mission District of San Francisco in the 1960's and 1970's. Mexican taco shops, known as Taquerías, began to create larger than regular burritos and used a steam table assembly method, complete with wrappings in aluminum foil. Popular fillings included carne asada (beef), Mexican style rice, whole beans (non-refried), sour cream and onion.
