Nopales Asados con Xoconostle, Sierra Gorda Otomí

Querétaro's Sierra Gorda, on the dry Otomí edge of the Bajío, is where this dish belongs. Thick nopal paddles go straight to the comal, no pot of boiling water, no vinegar bath, no tricks. The women who make this well know the cactus by touch: too young and it collapses, too old and it chews like rope.

Xoconostle is the authority here. Not sweet tuna. Xoconostle, the sour prickly pear that grows where the ground is stingy and the sun is not polite. It gives acid before limón arrives, and it tastes of that hard geography. Dice it with cebolla blanca, chile serrano, oregano de monte, and a whisper of chilcuague if you have the root. Limón supports the xoconostle. It does not replace it.

I first wrote this one down after a market morning in Querétaro, watching a señora score nopales with the tip of a knife and lay them on a comal dark from years of work. She didn't dice them raw because she knew what happens: baba everywhere and no char. Roast first, cut later. La cocina no es decoración, es trabajo.

Serve it in simple barro, with frijoles bayos if you want a meal, and warm corn tortillas. No flour tortillas here; those belong farther north. This is a 32-state cuisine. Así se hace y punto.
