Cabuches en Escabeche del Altiplano Potosino

San Luis Potosí, the Altiplano potosino, the dry high country around Matehuala, Charcas, Salinas, and Real de Catorce. That is where cabuches belong. These are the flower buds of the biznaga roja, gathered in spring before the cactus opens its red crown. The season is short. The appetite is not.

Cabuches en escabeche is Cuaresma food, yes, but it is also desert intelligence. When the land gives you a small green bud for a few weeks, you learn to preserve it in vinegar with onion, carrot, chile serrano, bay, Mexican oregano, thyme, and marjoram. The women of the Altiplano perfected this because they understood scarcity without making it sad. A jar of cabuches on the table with tortillas and queso fresco can carry you through a meatless meal and still feel like a privilege.

I first bought them from a señora outside the market in Matehuala, packed in reused glass jars with the carrots cut thicker than I would have cut them. She corrected me before I asked anything: blanch first, vinegar second, rest two days. She was right. The cabuche should stay firm under your teeth, like a caper that grew up in the desert and learned manners from nobody.

Buy cabuches only from vendors who know where they came from. Many biznagas are slow-growing, and some are protected. A good harvest leaves buds on the plant and respects the season. If the mercado does not have cabuches in spring, do not pretend with capers. Cook what the land is giving you. Cada estado, su propia cocina.
