Papa rellena

Papas rellenas are the most popular type of croquettes in Latin American regions such as Peru, Ecuador, Bolivia, Mexico, Chile, Colombia, and the Caribbean (more so in Puerto Rico, Cuba and the Dominican Republic). The dish is a potato-based dough into which a filling made of chopped beef and onions, whole olives, hard-boiled eggs, cumin and other spices is stuffed. Once prepared, the obloid mass is dredged in flour and deep-fried. Potato flour is often added to give greater consistency to the dough. In Peru, the dish is usually accompanied with a "salsa criolla", or an ají sauce. They consist of mashed potatoes stuffed with seasoned ground meat and various spices, and then deep-fried. The dish varies in preparation and presentation between countries. Papas rellenas are a local favorite in heavily Cuban-populated American cities such as Miami and Tampa, in which the Cuban version consists of potato balls stuffed with seasoned picadillo.
