The Mission-style burrito — a large flour tortilla wrapped around rice, beans, meat, salsa, sour cream, cheese, and guacamole, rolled into a tight cylinder and wrapped in foil — was invented in San Francisco's Mission District in the 1960s, either at El Faro or La Cumbre (both claim credit). It is not Mexican — Mexican burritos (where they exist, primarily in northern Mexico) are smaller and simpler. The Mission burrito is a San Francisco creation: the rice-inside-the-burrito innovation, the massive size, the foil wrap, and the assembly-line format (Chipotle's business model is directly descended from Mission taqueria service) are all specific to San Francisco. The burrito has become America's most popular portable Mexican-American food.
A large (30cm+) flour tortilla, steamed or warmed on a flat grill to make it pliable, filled with: Mexican-style rice (cooked with tomato and cumin), refried beans or whole pinto beans, a protein (carne asada, carnitas, al pastor, chicken, or barbacoa), salsa (mild, medium, or hot — the customer chooses), sour cream, shredded cheese, and guacamole. The tortilla is folded at the bottom, rolled tightly from one side, and wrapped in aluminium foil. The foil holds the burrito together and creates the eating format: peel back the foil as you eat.
1) The tortilla must be warmed and pliable — a cold tortilla cracks during rolling. 2) The rice goes in first — it absorbs excess liquid from the salsa and beans, preventing a soggy bottom. 3) Roll tight — a loose burrito falls apart. Tuck the bottom, fold the sides, roll firmly. 4) The foil is structural — it holds the burrito together and creates the peelable format.
La Taqueria (Mission District) was named "America's Best Burrito" by FiveThirtyEight — and their burrito contains no rice (a deliberate omission, arguing that rice dilutes the filling). The rice-vs-no-rice debate within the Mission District mirrors every other regional food debate in this database. The super burrito: all fillings plus guacamole and sour cream. The regular: no guac, no sour cream. The wet burrito (enchilada-style, smothered in sauce — a Midwest variation) is not a Mission burrito.
