Why Do Tacos Have Double Tortillas?

A street taco is made up of two tortillas. Especially when you add a little sauce or moisture to them, corn tortillas may easily become ripped apart. The additional tortilla serves as a form of protection, similar to ″grocery store double-bagging,″ as one Chowhound member described it. The second tortilla helps to guarantee that your taco does not break apart in your palm.
