Like Chas, it took me moving to California in my early 20s to try Mexican food and even then it was Taco Bell, but that was a good gateway drug to teach me what the various things were, like, I didn’t even know what a burrito was back then. After Taco Bell, I was open to try any place.
Back in Indiana as a kid, my sisters would make tacos out of some kind of kit, but those seemed exotic to me and I would just eat the meat and cheese.
