Cotija is a type of cheese originating from the town of Cotija in the state of Michoacán, Mexico. It is a crumbly, aged cheese made from cow's milk, known for its salty and tangy flavor. Cotija is often used as a topping for various dishes, including tacos, salads, and elote (Mexican street corn). This cheese is sometimes referred to as the "Parmesan of Mexico" due to its similar texture and use in cooking. Cotija can be found in two varieties: fresh and aged. The aged version is firmer and has a stronger flavor, making it a popular choice for enhancing the taste of many traditional Mexican recipes.
