Chilaquiles Horneados con Huevo en Cazuela

Chilaquiles are from the Valle de México. The word comes from Nahuatl, chilaquilitl, meaning chiles and greens, and the dish itself is older than the Spanish. This is breakfast food. Not nachos. Not a snack. Breakfast. The fondas in Colonia Roma and Colonia Doctores have been serving chilaquiles since before my mother moved to Ciudad de México, and they will be serving them long after we are gone.

The dish solves a practical problem: what do you do with yesterday's tortillas? You dry them out, you toss them in a salsa you built that morning, you melt good cheese into them, you crack eggs on top. Day-old tortillas are not a flaw in the recipe. They are the recipe. Fresh tortillas turn to paste the moment they touch the salsa, and you end up with a sad mush instead of chilaquiles that hold a bite at the center.

This version is horneados, baked in a clay cazuela. It is how my tia Carmen made them on Sundays when the family came over and she did not want to stand at the stove flipping individual portions. You build the salsa, you toast the totopos, you toss them quickly, you layer them with queso Oaxaca and epazote, you crack the eggs into shallow wells, and the oven does the rest. The cazuela holds the heat at the table and lets the dish keep cooking gently while people serve themselves.

The queso is Oaxaca, pulled into strands, not shredded mozzarella, not yellow cheese, and never anything that comes pre-shredded in a bag. The crema is Mexican crema, thinner and tangier than American sour cream. The epazote tucked between the layers is not optional. It is the herb that smells like the central highlands and it belongs with corn and salsa roja the way oregano belongs with tomato. My mother used to say: si no tiene epazote, no es de aquí. If it doesn't have epazote, it isn't from here. Saber cocinar es saber vivir.
