A tortilla chip is a snack food made from corn tortillas that are cut into triangles and fried or baked until crispy. They are typically made from masa harina, a type of corn flour, which gives them a distinct flavor and texture. Tortilla chips are often served with dips like salsa, guacamole, or queso. Originating in Mexico, tortilla chips have become popular in many countries, especially in the United States. They are commonly enjoyed as a party snack or appetizer and are a key component of dishes like nachos, where they are topped with cheese, meats, and other ingredients.
