The idea that authenticity is a fixed and rigid thing is absurd for a food culture that has gone through as much historic change and reinvention as Mexican gastronomy.

To declare that the only good Mexican food is “authentic” Mexican food also assumes that the cuisine has ceased evolving. Like so many international cuisines, Mexican food has thrived as it has adapted, and it isn’t done doing that.
