Gringas
Gringas are a variety of tacos which consist of a flour tortilla filled with cheese, al pastor, and pineapple. This is then grilled in the same manner as a quesadilla. Some attribute the name to the use of white flour tortillas. Its origin is attributed to two young Americans who studied Spanish at UNAM: Sharon Smith and Jennifer Anderson. The story dates back to 1969. The young women used to eat in a small establishment on Leibnitz Street in Mexico City, but since they did not like corn tortillas, they asked to prepare their tacos in a flour tortilla quesadilla. Other diners who also frequented this taqueria also began to order their tacos "like those of the gringa", giving rise to the name with which they are known to date.
