The blue corn enchilada lady is equally notorious and ephemeral. You know grilled cheese truck and its tweets? Well, this lady ain't having wi-fi nor a twitter account, so finding her is an awesome treat, pleasure and almost an honor since cops chase her business around town. So when you spot her, you better have plenty of cash ($2.50-$3 each) to indulge your cravings and support your community!
The common spots include Placita Olvera and Echo Park/Sunset Blvd. The typical fixings include: chicharrones, squash blossoms, chicken, potato, mushrooms, frijoles, chorizo and potato and huitlacoche (corn smut).
You choose whatever you want inside quesadilla and she starts shaping fresh blue corn tortilla from the masa, adds cheese and makes a quesadilla right on the stove in front of you. You can sprinkle it with queso, onions, cilantro and red and green salsa. Up to your liking, but be careful, that salsa is muy caliente!
