Amongst the best tortas in all of Mexico, and well deserving of a Chowzter prize, are the tortas of pierna con queso exclusive to Tortitlán, in San Miguel de Allende, Guanajuato. These bulging masses of goodness are stuffed with warm roast pork leg and grilled Oaxaca cheese, then spiked with pickled jalapeños. The fresh rolls are lightly crunchy and but retain their springiness. No amount of hyperbole can describe how good these caloric bombs are.
