National Taco Day is celebrated every year in Mexico. There are some previous mentions of Taco Day being celebrated on May 3, but that is no longer the case. In Mexico, Día del Taco (Day of the Taco) is celebrated on March 31.
The holiday in the United States can be traced back to the Mexican fast-food chain Del Taco, which began celebrating in 2009. Since then, other restaurants, including those at the local and national levels, have begun to offer specials too.
Tacos are thought to come from Mexico, long before the Spanish arrived. Ancient Mexicans used freshly made, soft, flat corn tortillas and gave them fillings like fish and cooked organs.
It was a staple meal that provided vital nutrients and energy to those who consumed it.
Mexican historian Jeffrey M. Pilcher’s theory, which has some more evidence to support it, is that the dish started around the 18th century in Mexican silver mines. He suggests this because the sticks of dynamite used in the mining process were referred to as “tacos” and had a shape similar to the dish we eat today
Authentic Mexican tacos involve corn tortillas, not flour. American tacos usually involve hard taco shells, while authentic Mexican taco shells are soft. Authentic Mexican tacos are not topped with cheese like most American versions. Instead, they are topped with fresh cilantro and finely diced white onion.
