While burritos are ubiquitous in U.S. Mexican restaurants, some argue that they aren’t an authentic Mexican dish. Indeed, the history of the burrito is a muddled one. Researchers have traced their origin to central Mexico in 1895 — likely the clever, practical result of wrapping just-cooked food in a tortilla to keep it warm — but they only exist today in the northern part of the country, the province of flour tortillas (as opposed to corn).
Throughout Chihuahua, for example, you’ll find small burritos of thin (and not super-glutinous) tortillas wrapped around just two ingredients: meat or fish and beans or potatoes. In other words, a real burrito doesn’t resemble anything we find today in the Bay Area.
