Guajolota

Guajolota , also known as a torta de tamal, is a form of street food commonly found in Mexico City and within the State of Mexico. It is essentially a sandwich composed of a tamal placed inside a bolillo or a telera, which is a rounder version of a bolillo. Vendors are commonly found selling tortas de tamal throughout the day near offices, markets, schools, and especially near churches on Sunday mornings. Most vendors sell a variety of tamales stuffed with different ingredients, such as red mole with chicken, salsa verde with pork, cheese and chile poblano "rajas con queso," or a "tamal de dulce," which is a sweet flavored tamal, to accompany the bolillo. Guajolotas are frequently bought with a hot drink known as atole, which comes in a variety of flavors. The order of a guajolota and atole are also known in Mexico City as a "guajolocombo."
