Bajío Sopa de Tortilla with Queso Ranchero

Guanajuato, in the Bajío, is where I place this bowl: León to the west, Querétaro to the east, San Luis Potosí pulling the road north, Aguascalientes close enough to argue about the cheese. This is sopa de tortilla in the register of the Camino Real de Tierra Adentro, not a tourist bowl with chips thrown on top. The broth is built from chile pasilla, a little chile guajillo, jitomate roasted on the comal, epazote, and manteca de cerdo.

Pasilla is the chile that defines it. It is dark, long, raisiny, and not designed to punish you. The guajillo gives clean red color. The women I watched in León and Querétaro cooked the puree first, frying it in lard until the fat took the color of the chile. Then they added the caldo. That order matters. Put raw blender salsa into broth and you'll taste raw blender salsa.

The finish tells you you are in dairy country. Queso ranchero crumbles over the hot broth, thick crema from the hacienda lechera softens the chile, and aguacate criollo sits on top with fried pasilla strips. If the Mercado Aldama has good xoconostle, use a wedge for acid. If a vendor in the Sierra Gorda offers chilcuague, use only a pinch. This is Bajío cooking: maize, chile, dairy, dry-country sharpness. Cada estado, su propia cocina.

My mother was Jalisciense, so this was not her house soup. The version in my notebook came later, from a cocinera in León who wrote in the margin: fríe la salsa, no la hiervas cruda. Fry the salsa, do not boil it raw. That is the lesson. Saber cocinar es saber vivir.
