Tacos mineros
Tacos mineros, or tacos de minero, are simple tortilla-wrapped meals linked by historians to the silver-mining districts of colonial Mexico, and the name is central to one of the leading theories about the origin of the word taco. They are commonly described as the ancestors of steamed styles such as tacos sudados and tacos de canasta.
Etymology and history
In an interview with Smithsonian Magazine, the historian Jeffrey Pilcher set out the theory that the taco dates to the silver mines of eighteenth-century Mexico. In mining slang, a taco was a small explosive charge: gunpowder wrapped in paper and pushed into a hole drilled in the rock face. A rolled tortilla holding a filling resembled that charge, and the name may have passed from the blasting cartridge to the meal miners carried underground. Pilcher noted that one of the first kinds of taco to be described in writing was the taco de minero.
The theory is not settled. Xataka México points out that the earliest dictionary and archival uses of taco for food date only from the late nineteenth century, so the eighteenth-century mining connection cannot be documented with the same precision. The same article mentions a competing derivation from the Nahuatl word tlahco, meaning 'middle', favored by some linguists, and treats the word's origin as an open question.
Description
Accounts of the miner's taco describe a modest, portable meal rather than a fixed recipe. Mexico News Daily, discussing the evolution of steamed tacos, says the tacos mineros of the mining camps were typically filled with refried beans and potatoes. Packed while warm, the tacos softened in their own steam by the time they were eaten, a quality that later defined tacos sudados.
Today the label is used more as a historical category than as a dish with standard ingredients, and cooks who revive it generally choose the same humble, filling combinations: beans, potatoes, sometimes chile-stewed meat, all wrapped in corn tortillas and kept warm in cloth.
Legacy
Mexico News Daily describes tacos sudados as having evolved from tacos mineros, and tacos de canasta as a later twentieth-century descendant of the same tradition, though a distinct style. Regional steamed tacos such as tacos tuxpeños are sometimes grouped with them under the broad family of tacos al vapor. Pilcher's broader research, as summarized by Smithsonian, also traces how the working-class taco spread from regional settings to the taquerías of Mexico City and eventually to the United States, where the word began appearing in newspapers in 1905.
