Pepito de Bistec

This is from Ciudad de México. Not generic Mexican, not Tex-Mex with a Spanish name. The pepito is a chilango sandwich, born in the taquerías and torterías of the capital, eaten standing up at a counter under a fluorescent light at midnight, or wrapped in paper for the bus ride home. Every neighborhood has its own version and every chilango has a favorite spot they will defend with their life.

The bread is the law. It has to be a telera, the soft oval roll with three creases on top, not a bolillo and absolutely not a baguette. The telera has the right ratio of crumb to crust to soak up the meat juice without disintegrating. The bistec is thin, fast, and hot off the comal, the kind of cut a taquero chops directly on the griddle with the edge of a metal spatula. The queso is Oaxaca, pulled into strands so it melts into the beans below. The frijoles have to be hot and made with manteca. Everything else is decoration. La manteca es el sabor.

I ate my first pepito at a stand on Avenida Insurgentes when I was nineteen, between classes at UNAM. The taquero chopped the meat on the plancha while I watched, slid it onto a split telera spread with frijoles, added the cheese, the avocado, the jalapeños from a jar he had refilled a thousand times. He did not ask me what I wanted on it. He knew. That is the pepito. It is built one way because that is the way it is built. No me vengas con atajos.
