The Cuban sandwich is an art form. There are a thousand improvisations, depending on the taste, level of talent, and materials available to the maker. But as with any school or period in the art world, there is a certain archetypal Cuban sandwich, the paradigm for anything that would presume to call itself a Cuban sandwich. Where is such a masterpiece found? It is at Enriqueta's. The archetypal Cuban sandwich has to be on pressed Cuban bread, and it must have just the right combination of ham, pork, swiss cheese, and pickles. How Enriqueta's cooks do it, turning out perfect copy after perfect copy, is a mystery of the creative spirit.
