Adobo Conventual de Vigilia

Puebla de los Ángeles, the convent city, is where this adobo belongs. Not as a plate, as a sauce. In the old kitchens around Santa Rosa, Santa Clara, Santa Catalina, and Santa Mónica, the nuns built sauces for the calendar: rich moles for feast days, lean adobos for vigilia, when meat and lard left the table and the discipline of the sauce had to carry the meal.

The chiles here are ancho and guajillo. Ancho gives dark fruit and body. Guajillo gives clean red color and a sharper edge. The acid is vinegar, not tomato. The perfume comes from garlic, Mexican oregano, comino, clavo, pimienta, canela, and a little ajonjolí, that Old World register the convent kitchens absorbed and made Mexican. No lard here. This is vigilia. The fat belongs to other days.

El metate es la regla. A blender will make a useful paste, and I won't pretend every home cook owns a volcanic stone metate, but understand what the metate does: it crushes the chile skins, garlic, spices, and sesame into one architecture. A quick blend gives you liquid. A proper grind gives you adobo. No me vengas con atajos. Toast, soak, grind, simmer, rest. Así se hace y punto.
