Tlacoyos are small, flattened masa pockets that are stuffed with either beans, cheese or fava beans and then grilled on a comal. They’re a Mexico City street snack made almost exclusively by women, and usually you can find them near any subway station, market or tianguis.
A well-made tlacoyo has a crisp exterior, creamy innards and a tang from a drizzle of salsa and a handful of diced nopales on top. They’re also healthy, since most tlacoyeras don’t add oil.
I have enthused about them before. But I’m not sure if I’ve ever made it clear that tlacoyos are actually my favorite Mexico City street snack. A freshly made tlacoyo is — as I have just learned in my slightly vulgar Mexican slang dictionary, purchased in the Centro Histórico — chingonométrico.
Here are some of my favorite tlacoyo photographs that I’ve taken over the years.

A tetela, similar to a tlacoyo but smaller and triangle-shaped. We made this one at Susana Trilling’s cooking class in Oaxaca.
