A taco is a “tortilla with something wrapped inside." Again, as with enchiladas, the central ingredient is the tortilla, which is made from corn and should not be mistaken for a Spanish version of the same name that is made of eggs and potato. Dating from the time of the Spanish conquest, Bernardino de Sahagun provides a list of the various types of tortillas that the Spanish encountered in Mexico. These are:
tlaxcalpacholi – a color corn flour tortilla.
ueitlaxcalli - which translates as a very thin, large, white tortilla.
Quauhtlaxqualli – a large, white, thick, coarse tortilla made with nixtamal, and totonqui.
Tlaxcalli – which refers to the common white tortilla ?
According to Avernin, a “taco” is “definitely not: A canary yellow tortilla with black spots” . Therefore, the hard, curled up holders typically called “tacos” in the US are nothing of the kind.
Bernal Diaz Del Castillo documented the first taco feast enjoyed by Europeans and Cortes himself arranged for the banquet in Coyoacan for these captains. However, the taco predates the European invasion as anthropologists have found evidence that the people living in the lake region of the Valley of Mexico traditionally ate tacos filled with small fish. As this suggests, the content of a taco differs with geographical region, but also, with the time of the day, as there are “early morning tacos, evening tacos and late night tacos.”
