What is authentic Mexican cuisine? Ancient dishes like bírria, menudo, and chochinita pibil are the easiest to categorize as authentic because of their age, but what about colonial dishes like chiles en nogada or mole poblano? Tacos al pastor and tacos de pescado were brought to Mexico even more recently by Lebanese and Japanese immigrants. Are these dishes still "Mexican?" The more recent the dish, the trickier it becomes to call it authentic. Unless of course, we agree that Mexican cuisine is constantly evolving with new dishes being created all the time. In this sense, Pujol has evolved significantly since my first visit in 2010. It is now not only a restaurant that recreates ancient dishes, but a restaurant that pushes Mexican cuisine forward by creating new ones. In the beginning Pujol looked inward at Mexico's rich culinary history, cataloging, studying, and improving upon very old dishes. Pujol still does this but with more confidence, now looking outward as well, placing one of the oldest cuisines into the context of international dining.
