The Birth of the Taco in Mexico

The taco is said to have originated in Mexico during the pre-Columbian era. In those times, tortillas were made by grinding corn into a dough and then flattening it into a round shape. The word “taco” is believed to have come from the Nahuatl word “tlahco,” meaning “half” or “in the middle,” as the tortillas were folded and filled with various ingredients, placed in the middle, and then eaten by the Aztecs.

The earliest known taco filling was a small fish brushed with chili sauce and cooked over hot coals. Indigenous groups also filled their tacos with a variety of ingredients, such as insects, small birds, and fruits like avocados and guavas. The use of meat, particularly beef, as a filling, was introduced after the arrival of the Spanish in the 16th century.

Tacos Migrate to the United States

The taco’s journey from Mexico to the United States can be traced back to the early 1900s when Mexican immigrants crossed the border in search of work. As they settled in cities like Los Angeles, San Antonio, and San Francisco, they brought their culinary traditions with them. However, it wasn’t until the 1950s when the first Taco Bell opened in California, that tacos saw a surge in popularity in the US, becoming a fast-food favorite.

However, the tacos served in the United States took on a more Americanized version, with crunchy taco shells, ground beef filling, and cheese as a topping. This popular style of taco is known as the “Tex-Mex” taco, and it continues to be a go-to comfort food for many Americans.

As tacos spread across the globe, they began to take on different flavors and fillings, resulting in unique regional variations. Let’s explore some of these delicious taco varieties:
