My grandmother has been making tortillas since before I was born. I've always loved her tortillas, I could eat tons and tons of the damn things. When I started cooking, years ago, I started asking her for her recipe. I wanted to know how to make them as good as she does. She always said that she didn't remember. One time, she gave me the wrong recipe. Since then, she claims she doesn't know how she makes them. But she still makes them, and they're still amazing.
After trying to get the recipe for years now...
I gave up and found a random recipe on the internet. They're not nearly as good, but they're still worlds better than store bought crap. Not sure why the stubborn old lady refuses to part with her recipe, but it's cool.
