Tostilocos (also Dorilocos[1]) are a popular Mexican antojito (street food) that consist of Tostitos or Doritos tortilla chips with various toppings.

Ingredients can include white corn, cueritos (pickled pork rinds), cucumber, jícama, lime juice, Clamato, mango pieces, hot sauce, chamoy, chili powder, salt, mayonnaise, and Japanese-style peanuts (sometimes referred to as "cracker nuts").

[4][5] The original mix contained tortilla chips, cueritos, cucumber, jícama, rueditas (little wheel-shaped pieces of fried flour), Japanese peanuts, lime juice, chamoy, and hot sauce.

[4] The usual way of serving tostilocos is by cutting open a bag of tortilla chips lengthwise and adding chamoy, lemon or lime juice, and if desired, Valentina hot sauce.

[4] Tostilocos is generally a "no rules" type of dish, so the ingredients may vary depending on personal taste.
