Campechanas de Santa María del Río

San Luis Potosí, Santa María del Río. This sweet belongs to the small town south of the capital, the same place famous for rebozos woven with hands that know rhythm and patience. The campechana is not a soft cookie. It is a sheet of laminated dough, brittle and glassy on top, with layers that break into flakes when you bite it.

The fat matters. Use manteca de cerdo. Modern bakeries sometimes use vegetable shortening because it is cheap and predictable. I understand the business reason. I don't respect the flavor. Lard gives the pastry its clean snap, its savory shadow under the sugar, and that old panadería smell you cannot fake with a plastic tub of shortening. La manteca es el sabor.

I learned this version from a woman in Santa María del Río who kept her campechanas in metal trays lined with brown paper, stacked beside baskets of pan de pulque. She folded the dough with the same discipline her neighbor used to fold silk thread for rebozos. No me vengas con atajos. The dough rests, the fat chills, the sugar caramelizes, and then the pastry tells you whether you were patient enough.

This is a 32-state cuisine. Not everything Mexican has chile, tomato, cilantro, or lime. Some dishes are wheat, lard, sugar, and technique. Cada estado, su propia cocina.
