A burrito (US English /bəˈritoʊ/, About this sound buˈrito ), or taco de harina [ˈtako ðe aˈɾina], is a type of Mexican-American food. It consists of a wheat flour tortilla wrapped or folded into a cylindrical shape to completely enclose the filling. (In contrast, a taco is generally formed by simply folding a tortilla in half around a filling, leaving the semicircular perimeter open.) The flour tortilla is usually lightly grilled or steamed, to soften it and make it more pliable. In Mexico, meat and refried beans are sometimes the only fillings.
