In his Gran Libro de Tortas, Roberto Arturo Ayala T. lists the five components of a great sandwich: bread, spread, filling, garnish, and ingenuity, but also points out that a great sandwich is not necessarily a giant sandwich, and that tortas can be eminently simple. In the Yucatán, specifically in the town of Merida, tortas are made of nothing more than a bolillo (a plain, slightly crustier roll with just a single rib down the center, as opposed to the three humps of a telera), and cochinita pibil, the slow-roasted pork dish typical of the area, made with achiote paste and sour orange juice. The rich, meaty juice from the pork drips into the bread (hence the need for a bit more crust) and acts as the spread. A little acidic, spicy salsa or a few pickled purple onions provide contrast, but this sandwich is truly just two parts: meat and bread. Cohinita pibil is so full of natural talent that what it needs more than anything is for all its teammates to get out of the way so it can score all the touchdowns.
