I had some street food for lunch the next day.
First, a quesadilla from Jenni’s Quesadillas in Roma Norte. Her stand is at the intersection of Colima and Merida. The menu consisted of quesadillas, pambazos, which are a bit like tortas, and tlayocos, which are masa ovals stuffed with beans and topped with various toppings. I just had one quesadilla with squash blossoms / flor de calabaza. The tortilla is made from fresh blue corn masa and had a very good flavor and texture. Lots of squash blossoms and some Oaxaca string cheese. I added some of the green and red salsas from the stand. A delicious quesadilla, and quite juicy.
Then I had a shrimp tostada from the Mariscos Orizaba stand in the Juárez neighborhood which is just north of Roma Norte, on my way to see the Angel of Independence. Very good, a crispy tostada spread with (optional) mayonnaise, topped with some nicely cooked shrimp, cilantro, onions, avocado slices, and some sort of sauce or relish that was maybe vinegar based.
