Cotija is a crumbly, salty Mexican cheese made from cow’s milk and named after a town in the state of Michoacán in Mexico. It is aged for two to twelve months and has a crumbly texture that easily breaks apart for garnishing dishes like this Mexican Street Corn Salad. Cotija can be found at most major grocery stores in the U.S. or Latin American markets. If it’s not available, you can substitute feta or another crumbly cheese.
