Quesillo is a term used in several Spanish-speaking countries to refer to different dairy products and desserts.
In Mexico, quesillo denotes a semi-soft, string cheese from Oaxaca, made using the pasta filata (stretched-curd) method, similar to Italian mozzarella; it is commonly used in tlayudas and other local dishes.
In Venezuela, quesillo refers to a custard dessert similar to flan, traditionally made with eggs, condensed milk, whole milk, and caramelized sugar.
In the Canary Islands, quesillo is also a type of dessert flan but typically includes condensed milk and is characterized by its firm and creamy texture.
In Nicaragua and El Salvador, quesillo refers to a soft, creamy cheese often eaten with tortillas and pickled onions.
