Doritos is an American brand of flavored tortilla chips produced by Frito-Lay, a wholly owned subsidiary of PepsiCo. The concept for Doritos originated at Disneyland at a restaurant managed by Frito-Lay.

A tortilla chip is a snack food made from corn tortilla, which are cut into triangles and 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.
