Frita Cubana (or simply frita) is a burger variety with Cuban origins. It was invented in Havana in the 1930s, 1940s, and 1950s (there's still no consensus). Originally, these burgers were sold by friteros from their stands, called puestos.
The burgers were made with Cuban rolls, ground beef, onions, seasonings such as smoked paprika (pimentón), and julienned potatoes. In 1962, Ramon Estevill brought the burgers to Miami when he opened his small eatery. Nowadays,
El Rey De Las Fritas is the most popular frita joint in Miami, and the fritas are made with a spicy tomato sauce, ground beef, a soft bun, red onions, and salty shoestring potatoes.
