Tacos Campechanos

Campechano describes a manner of building the taco — a mix of meats on one tortilla — rather than a regional dish, and despite the name's echo of Campeche state, in the taquería it simply means a combination. It is a Mexico City and central Mexican griddle-stand standard with no single recorded inventor, born of the practical logic of a stand that already cooks several meats side by side and combines them on request. The Spanish adjective campechano, meaning easygoing or all-mixed-together, is the likely source of the usage. The honest framing is a street-stand combination taco defined by its mix, not a dish with a fixed origin date.

A layered, savory mouthful: the beef gives clean meaty chew, the chorizo a spiced, slightly sour, deeply red richness, and the longaniza a sweeter, fattier note, all bound by the sausage fat the beef has soaked up on the griddle. It is the fattiest and most assertive of the everyday tacos, hot from the chorizo's chiles rather than from salsa alone. Onion and cilantro cut the fat, lime brightens it. The pleasure is the way no single flavor dominates — every bite carries beef, spice and sausage at once.

The technique is the mixing on the griddle. Chorizo and longaniza are raw, fatty, chili-seasoned sausages; as they cook their fat renders out and pools on the steel, and the chopped beef is folded through it so the meat fries in seasoned sausage fat rather than dry — that fat is the flavor carrier, since the chiles' aromatic compounds are fat-soluble. Chopping everything together on the hot surface maximizes contact, so each piece of beef takes on sausage character. Keeping the meats separate, or draining the sausage fat, gives a weaker, drier taco; the point is to let them cook into one another.
