Tacos de Chileajo Mixteco

This is from the Mixteca region of Oaxaca. Not the Central Valleys, not the Isthmus, not the Coast. The Mixteca. Most people who say they know Oaxacan food have never eaten Mixtec cooking, and that tells you how much work is left to do.

Chileajo is a chile-and-garlic braise. The name says it: chile, ajo. The guajillo does the color and the base heat. The garlic does the rest, and there is more garlic in this recipe than most cooks outside the region would believe. A full head, sometimes more. That is not a mistake. That is chileajo. The vinegar, cane or pineapple, cuts through the fat and gives the paste its edge, the sharp, bright acidity that keeps a heavy pork dish from sitting like a stone. The oregano is dried Mexican oregano, the kind the senoras in Huajuapan de Leon crumble between their palms before it goes into the blender.

I collected this recipe in the Mixteca Baja, from a woman who made it for Day of the Dead every year in a clay cazuela the size of a wash basin. She cooked the pork in lard first, then buried it in the paste and let it go for two hours until the meat fell off the bone and the chileajo had thickened into something you could spread with a spoon. She served it on tortillas she pressed by hand while the pot simmered. No plates. No forks. Just tortillas, onion, cilantro, lime, and the paste-covered pork piled in a clay bowl on the table. My mother would have recognized the logic: you build a meal from a single pot and a stack of tortillas. Saber cocinar es saber vivir.

Do not confuse this with mole or adobo. Chileajo is its own thing. It is drier, more concentrated, more direct. The paste clings to the meat instead of pooling around it. When you pull the pork apart and pile it onto a tortilla, the chileajo comes with it. That is the point.
